Predatory business model relying on extensive and extortionate charges hidden in their initial fee. Understaffed and unhelpful customer service.

Worst ever provider! Service is really inconsistent, worst ever customer service and got charged extra a number of times. Unacceptable!

Appalling customer service avoid at all costs. I have contacted over 6 times to cancel a contract and yet they have still charged me. They say to use the chat then they don't respond, you can't email and they don't pick up the phone when you call or just as they have now they say the microphone isn't working and tell you they will call back but never do. Completely unacceptable and a scam. AVOID

It was an easy set up process but did take 2 weeks. Leaving is where the real problem lies… they’ll end your contract but keep on charging you monthly where there is a 30 day notice period to cancel. It may be cheaper while you use it but leaving has cost me an extra £200. Do not use Onestream!

Stay away from these Scammers I'm not with the. But they still took £800 out my account. Avoid like the plaige

THIS IS THE WORST CUSTOMER SERVICE I HAVE EVER HAD.NO ONE DO THE JOB, THEY MAKE SURE YOU LOOSE IT BY NOT PROVIDING ANY IMFORMATION.THIS IS DISGUSTING.IF ANYTHING HAPPEN TO MY ORDER TODAY ONESTREAM WILL BE RESPONSIBLE .I WANT A MANAGER TO GET IN TOUCH WITH ME ASAP

Would give 0 stars if possible. Complained about slow internet nearly 4 weeks ago, Onestream replied to say they could see our service was not performing as expected and they would send an engineer to look at this, threatened us with £199 fine if we missed the engineer appointment, engineer never even showed up. Sent 2 subsequent emails which were ignored, finally just cancelled our direct debit, threatened again with a £295 fine for "breaking the contract". Phoned them to express the frustration and were told that infact an engineer DID come to our property, but "only needed to look outside" (very convenient!), they are absolutely adamant that we cannot leave our contract despite awful customer service, constant threats of fines for things, and admission that they were not delivering a level service that we were paying for. However attractive their prices look, just save yourself the trouble and go elsewhere!!

Awful equipment. 12 months contract and despite asking for help with buffering service, I was just told to switch a button on and off. Returned the equipment by hand on the last day of the contract on 9 th June 2026. The Company then insisted that by law I had to have broadband and then billed me. Constantly adding fees to this amount for late payment! Be careful if they want your debit/credit card details. They will attempt to use this to pay off fictitious sums! I took them to the arbitration service they'd signed up to. They agreed compensation. Then I received numerous emails and texts threatening my credit record. This was only resolved on 12 the September.
