Sumo Avis 

Great customer service! Michael explained everything in detail & was very helpful. His help was very much appreciated

Very poor service. Customer service is pathetic. They say that their business hours are between 9 am to 5:30pm but stop answering calls at 4 pm.

Be aware of the Sumo website. When you select an electricity plan, it changes the tariffs and rates one the next window. Check to make sure it's not ripping you off by doing a sneaky rate change. Gotta love power companies...

I am appalled by the customer service at Sumo. I contacted them – I spent an entire morning waiting to speak to a customer service person – to arrange for my electricity to be disconnected Monday third of August. I now have a tenant in the property – they moved in yesterday 5th August. Sumo did not disconnect the power as promised and I’m concerned that I’m paying still paying for the electricity – I have spent in more than two hours yesterday and today trying to contact Sumo by telephone – I am going to the ombudsman about this. I’ve had problems with other accounts when I have taken on commercial shops and have had to go to the Ombudsman to get them to sort out Sumo‘s inefficiency - this is a really inefficient company and in the past I have had customer service officers been quite rude to me. I will never deal with them again.

Extremely proud customer service Very professional and helpful

my call was handled really well.
the call taker was extremely helpful and very pleasant to talk to.
she has given me some options which will assist us in handling our Sumo bills in the future

I spent over 5 hours on hold today (Monday) and we haven’t had any power since Friday. It is Melbourne winter and with no power we also have no access to gas as the pilot light went out and only way to re-light it is with electricity. This is unacceptable. I am extremely disappointed in their contact options. I would not go with them if you ever want support or to talk to someone about an urgent matter. The only excuse they gave me after over 5 hours and missing my shift, no heating, no ability to cook or keep good in the fridge, was that they have a new cheap offer so there is lots of calls. I am so unhappy.

Shannon was very polite and friendly as he helped me set up payment assistance. I really appreciate it, especially the time he was willing to help me with a form over the phone. Fantastic customer service, thank you.

Sakti is top-notch! He was extra helpful and relentless and finding a solution to my concerns. Very well done Sumo team!

John was amazing he helped me get everything sorted was very professional and perlite this man deserves a raise

A very happy experience with sumo power they were very understanding and friendly to me and making sure that my experience was the best in my opinion, I was pleasantly spoken to and reassured that they were able to help me with my situation and any future challenges. I am very thankful to them and grateful for their support and support and understanding of my situation of financial difficulties that have not been resolved yet another reason why I would like to continue to be with sumo, and thank them so greatly in the meantime and thank them for all their help in the future as they continue to be my utilities supplier.
Kind regards Jure George from the bottom of my heart sincerely, thank you.

Tried calling through to customer service to try and switch from our current electricity provider to Sumo and was put on hold each time for more than an hour. Last call was 2 hours on hold and just gave up in the end. If they don't answer their phone how can they be any good? Unbelievable.

Spoke with Allan, really appreciate the help. sorted me out with the best suited plan for my situation. Great service.

I’ve had a very positive experience with Sumo Power. Their customer service team has always been friendly, professional, and helpful whenever I needed assistance. They responded to my questions promptly and made the process easy to understand. I appreciate their support and would happily recommend Sumo Power to anyone looking for a reliable electricity provider. Thank you for the excellent service!

The person on the phone, very helpfull
BUT then went on hold 1hr and 18 minutes to get on a better plan also went online and they said ring Sumo So you can see why I will be looking to leave Sumo
I dont have hours to sit on the phone .

Great Customer Service and payment plan options.
Great understanding of circumstances.

I have been with Sumo for a long time, and I am very happy with both their electricity and gas services. They have always provided reliable service at competitive prices. Their customer service team is friendly, professional, and always willing to help whenever I have a question or need assistance. My experience with Sumo has been excellent, and I highly recommend them to anyone looking for a reliable energy provider. Thank you for the great service

I was able to understand easily everything that was explained, I felt as if I was understood and not judged and I got the help that I needed, a very good transaction

I have been with Sumo for over a year now and very happy with the service and the rates. I just spoke with Joel a staff member who was fantastic as we are moving house and he was incredibly helpful. Another great experience I have had with Sumo.
