Halo Verify Avis 

Total unprofessional jokers.
I’ve called their call centre 3 times - which means waiting 1h to speak to an agent each time - and all 3 times they confirmed me their rapid test was ok to travel abroad (not valid for the day 2 and day 5 in the UK, but valid abroad and came with a certificate and QR code).
I make the order and nothing arrives, so I call them back (1h waiting again) and the agent had the courage to tell me “Oh, you are one of the lucky (!!!) ones who got the order cancelled due to a system error” - no refund and no notification of this... DISGRACEFUL.
I do the test the day before my flight and the confirmation and certificate does not come. It is a Sunday and the call centre closes early. I get through someone in Twitter and they say “we are chasing the laboratory”, “there is a system error”, “your result and certificate is coming soon”... until 2am - over the phone I was told “for rapid tests you get the result within 1h”.
The morning of my flight arrives and after 1h queue I manage to go through “Dona”, the worst agent I have found in my entire life as a customer. She does not give her surname for data protection, she tells me that all previous times I was given the wrong info and their rapid test does not come with the certificate, she is totally unwilling to understand my situation and to offer any kind of assistance. She has an extremely rude attitude. I’ve asked her to be put through to a manager or supervisor and she said she can’t do it, she can raise a complaint and a manager would follow up within 24h. I tell her what to write but she is faster in typing than me in talking... of course 2 months later I am still waiting for the manager to call me back!!!
Finally I had to run to a local pharmacy and get a proper test, and I have almost missed my flight thanks to Halo!
I will never ever use them again, and I would not recommend them to my enemies.

1st April 2022 update - Total jokers, despite the message below NO ONE has ever approached me, they clearly have no interest in addressing complaints or make things right. Let me make it clearer: AVOID AT ALL COSTS!!

What a horrible idea having to spit for 20 mins after a flight to fill up 2ml of saliva (which makes you dry already and you can't drink water). It was the most uncomfortable and waste of time when you're busy travelling.

The process was straight forward and easy. Plus, the staff was a gem! Would Definitely recommend.

I didnt receive my results until after I contacted the company and asked what was going on - just ad I was leaving the country 8 DAYS LATER! ...I have proof that everything went through - with an email from the company. They say it wasn't registered properly (again...I sent them email proof it said it was - the email THEY SENT ME SAYING TO AWAIT RESULTS), so their fault. I asked for a refund. They said no.
Do NOT USE THIS COMPANY! TOTAL SCAM!

The actual test & results process was super easy and I received my results in the time expected. The staff were generally helpful and the test location was easy to find. However, be prepared to walk.
That said I wasn't aware that I had to download the Halo app and had to do this at the reception of the test area. This was unexpected and a bit stressful, I would have downloaded the app and registered in advance if I had known. And I wasn't the only one. Halo is lucky that their customers can piggyback off the Sofitel's guest wifi. In addition I didn't receive a results email, I got it through their website. Again, not a huge problem but I had expected to receive an email as that what their website states. Overall, this is a good service and in my case my results were delivered the same day after a 5pm test.

A professional and straightforward experience.

The staff were excellent and extremely helpful. I would likely still be there if the gentleman had not assisted me😂

Results not returned, no help from hotline

I had a few issues with the Halo App but following a quick call to the customer service team Danielle was beyond helpful in guiding me through the process and booking a the courier service on my behalf to ensure my results arrived on time. Travelling alongside all the additional documentation that’s need can be stressful, so I’m extremely grateful to Danielle for making this hurdle such a smooth one!

HALO is great if you are flying into Heathrow. All very efficient and good vfm.

Everything up to the delivery of the result of my test was done very well indeed but then it took five days to send me the e_mail of the result which was not helpful!

Quick process, polite and efficient stuff who took me through the process in great manners.

It’s very very bad service and I was too long they give result very very late because they no put in mashin so I miss the flight and I was going to pakistan because my Father passed away

Pleasant helpful staff and quicker than expected results! Thank you

Very quick and efficient service
I could not thinking of other service like that
5 start

Did not give results within specified time. Given this was the only selling point of the company in the first place, this is not acceptable. Testing centre was completely disorganised.

This is the second time that I have used Halo, and both times you have provided a first class service. The second time you had a desk at the hotel ( Sofitel Heathrow T5) and your staff were very helpful. My only thing is that your costs are a little expensive, but for the service that you provide, it is worth it. thank you.
