Optimum Avis 

same old song and dance with missing account credits and fake billings. I canceled my account prior to my billing cycle, I save saved the email Optimim sent to me and showed them the email after I was billed for the month of service.. they totally disregarded and did they could find any records of credits.. I attached the email to the chat and was told it was wrong.. suck BS and poor customer service

Genuinely the worst service I’ve ever experienced in my life. An hour and a half of dropped calls for them to say I have to wait until tomorrow. I genuinely cannot wait to cancel this POS SERVICE.

Wow!! I used these guys for 18 months because it was my only option at the time. The install was the worst service experience I’d ever had and left a review for that in 2025. Including how their service agents lied to me multiple times and the field staff drilled a massive hole into a window frame on my brand new house.
I called 2 weeks ago requesting a disconnection date for 2 days later. I then asked if I would be refunded a prorated amount as they bill a month in advance and I was disconnecting only a couple days into a new cycle.
I was told yes to the refund and that I’d receive an email confirming the disconnection for 2 days later.
The only thing I received was multiple sales calls trying to get me to sign up for service in my new location. I purposely let the agent I initially spoke with know I was moving out of the country and not interested in ever using them again. But clearly my reason for disconnecting was not noted based on the ridiculous amount of sales callls I was spammed with.
After 2 weeks of still no confirmation, I called to see what was going on.
I was then told it would only be disconnected at the end of my current billing cycle and that they don’t do refunds but would offer me a discount if I set up service at my new location 🤦‍♀️
You cannot make this s*#t up!
Worst company ever with untrained employees.
Run far and fast. Do not waste your time and money with the guys.

Horrible experience - broke my phone number during porting now a week later I cannot receive non iPhone text messages. Switching back to Visible by Verizon. DO NOT USE OPTIMUM MOBILE

I do not feel comfortable even giving one star! They don’t deserve any at all! The service is horrible. I believe they are fraudulent by promising a year rate only to have a go up a month their technicians unless they are in-house or un knowledgeable and a complete waste of time. The remote that they sent out are cheap and don’t last for over a month then they send out replacements, which just a bad and technicians who can’t even program them. It’s now a month and I’m still waiting for a decent running remote. How does this company get away with us? It should be a class action suit if nothing else.

Such a bad provider. Customer Reps lies repeatedly.Had to call them 3 times to discontinue service.Every single time CR confirms confirmed disconnection but every single CR had to do it 3 times.Meaning every one of them lied. Asked them to disconnect from July 1 but they did not.Just a crappy provider to ignore at all cost.

Optimum has the WORST internet that I've ever experienced. I've been in a third-world country, and Optimum makes the internet there light-speed in comparison. I work from home and it keeps dropping me from my meetings. It's so spotty and inconsistent that it would literally just stop working at random times. Don't even think about gaming. Unfortunately, they have a contract with our development, meaning we have no choice but to endure this bullshit.

Hello,I had an issue with my stream box and the guy came out name Tony he was very great with fixing the issue .I would recommend him to come fix any problem u may have in the future!!!!

Everything listed in the above is 100% true! It took me over 40 minutes to cancel my service. Stay far away from these guys!!!

Switched to Optimum mobile after being promised an excellent promotional deal ($20/line for 18 months and $600 in trade-in credits). Once my numbers were ported over, their customer care team refused to honor virtually every single incentive used to get me to switch.

After endless phone calls and escalations, they only offered a tiny fraction of what was originally agreed upon. Classic bait-and-switch tactics. This was my first experience with Optimum and it will definitely be my last. Misleading, dishonest, and completely frustrating.

AVOID like the plague

I had a very disappointing experience canceling my service. Before canceling, I specifically asked whether I would owe for another month, and the representative assured me I had made the cutoff and would not be charged. Based on that information, I proceeded with the cancellation.

To my surprise, I was later billed for an additional month. When I called to dispute the charge, the company refused to honor what their representative had told me. Instead, they simply pointed to their policy and took no responsibility for providing inaccurate information.

Mistakes happen, but what matters is how a company handles them. In this case, there was no accountability and no effort to make things right. If you choose this provider, make sure you get everything in writing because you may not be able to rely on what you’re told over the phone.

Optimum is absolutely the worst company period. I just wasted over 30 minutes trying to tell them I don’t ever want their service. I told them if it was free I would not want it. Their retention team are basically hired harassers. I told them in every way I could I would never use their service. They kept putting me on hold and then the harassment would start again. There should be some laws against this tatic. Of course I don’t want even waste time discussing the money lost waiting for them to never come and install a fiber network. . Don’t use them no matter what freebies they offer. I have had their 37 years too long. I never write reviews because I don’t have time. They are that bad

Trying to access customer service in general or cancel my service with Optimum has been an absolute nightmare. You cannot get a person to speak to until you use the word "disconnect" Then their disconnection process is predatory. Instead of processing my request to cancel, the agents subjected me to incredibly aggressive marketing tactics and relentless upselling.Every time I stated that I just wanted to disconnect, they ignored my request and tried to push new promotions, bundles, or mobile plans on me. It is incredibly frustrating to be held hostage on a call just to stop paying for a service. They make it intentionally difficult to leave, showing zero respect for the customer's time or boundaries. It took two tries and 37 minutes on the phone to cancel. If you are considering Optimum, be warned: they will make your life miserable when you try to cancel.

I switched to Optimum mobile because I have their internet and I figured they're on the T-Mobile network save myself some money. Huge mistake. For the amount of frustration on The Daily that I get from lack of service it is not worth the money saved. It's about $15 a month I save and I can tell you I have decent service maybe once or twice a week. For our company who is almost a monopoly on Long Island running their wires all throughout Suffolk and Nassau and they're on the T-Mobile network somehow has the worst service I've ever had and I have had AT&T T-Mobile mint visible through Verizon and Boost Mobile and none of them have been this bad. The service is absolutely terrible. There are way too many dead zones. I understand it's 30 bucks a month but I seriously barely get service. I definitely do not recommend

I have had the worst experience I have ever had with optimum Mobil. We have been a faithful always paid our bill on time customer for several years now. We wanted to discontinue our service and go with our starkink because it is better internet service. Optimum is always going out. We called and they offered us a “Permotion” And got my husband con’d into getting the Mobil service and then lied about the promotion. So now we are stuck paying for mobile service that we wanted to discontinue AND “ CANT” Becausr their can’t speak English people got him on a 3 year contract!!!! Don’t fall for their permotions!!! They are con artist tbat all have rude customer service!!! I’m not ever going with optimum again S soon as his contract is up we are gone !!! And if I was anyone I wouldn’t go with them either”THEY SUCK”!!!!!

Why is Optimum aloud to monopolize areas in New Jersey? Years back I had Verizon internet now, for some odd reason, Optimum is the only supplier for cable and fiber internet. HOW IS THIS POSSIBLE? I have no other choices!!!

Went through 6 agents to get my problem fixed
Do not use the chat system

I have been an Optimum customer for over 5 years, and their home internet service has been extremely disappointing. The service is often slow, lagging, or completely down, and when you need help, you'd better plan on spending at least 30 minutes on the phone with little to nothing resolved.

Today was a perfect example. The cable from the utility pole appeared to snap and fall down, which caused my internet to disconnect. I explained this clearly to the agent, but instead of listening to the actual issue, she insisted I go through the basic modem reset steps. Resetting a modem does not fix a snapped or fallen cable.

To make matters worse, I explained that I have been paying $115 per month for 1 Gig internet while Optimum is advertising the same service online for $45 per month for new customers. I asked if there was any consideration they could offer for a loyal customer of more than 5 years. The response was simply, “No, cannot help you.”

Poor service, poor reliability, and poor customer support. I regret staying with Optimum this long and would not recommend them.

Pathetic ability to get an outside of my house broadband signal resolved. Any technical follow up calls to get any results runs me through a gauntlet of troubleshooting equipment inside my house. This has been done multiple times and a technician from Optimum has been to my house and verified that all in the house is fine and the signaled being delivered is a problem.

I pay for 1Gig of internet speed and I am receiving less than100Meg of speed!! My Neighbors are complaining as well. This has gone on for months!! Verizon or any other provider is blocked from being a provider.

optimum mobile lied about the price. promised 20$ per month for 5 year lock for internet 500mbps and 2 phone lines with first 3 months free. but charges 95$ initial fee and then 53$ every month.
