Bad service

I phoned to cancel my decoder and someone at the call centre told me its cancelled but till today it has not been cancelled and now I am told that I am owing. Shanaaz says I was called 3 times to confirm that I want to cancel but was unreachable yet no one left a message and apparently my phone rings for about 5 minutes before going to voicemail, I called my phone while she was on the phone with me and it did not even take 1 minute to go to voicemail. <br> I don't understand how they can say they need a voice recorded conversation to confirm that I cancelling when all their calls are recorded. <br> They already have 2 voice recordings of me saying I want to cancel.<br> I feel this is ******* and I need to be refunded for the money that I have charged.
