Terrible service from Supersonic Accounts!

My line got cancelled by Octotel last year November, SuperSonic then ‘created’ a new contract for me as they couldn’t tell me why this had happened. With their special running I would then be paying the discounted rate for the next 3 months. End of November my bill was more than double, I contacted them the 3rd December to find out what was happening. Ticket logged and they would come back to me. End of December the same thing - phoned them again on the 7th January 2026, and the same answer but this time my issue would be escalated. I contacted them again in the 19th Jan as no feedback as yet, asked to please give them 24hrs to respond and it would be escalated even more. They have acknowledged that this is an error on their side and I will be getting my refunds from last year. I waited and today contacted them again, more than 24hrs later, and guess what….they will escalate it….. I waited for more than 30min (at my own cost) for someone to get back to me as I wanted someone more senior, but eventually I put the phone down as they clearly had no intention of coming back to me!!!!!
