*****s your money -- and complaint process is impossible, by design

After 2 years' really bad service, I cancelled my contract once the time was up. This was in March, but I'm still having debit orders taken off every month. It's theft. I have tried to get hold of people to assist but a) calls don't go through b) in-store they tell you you can't have billing queries dealt with there c) on the consultant chat they tell you that the amounts are correct. After providing proof, they say "oh it should have been cancelled we'll do this now" -- I've spoken to THREE different people on THREE separate occasions. You can't request a reference number for these, but I've kept the transcript of two of them. I'll be taking legal action.
