I've cancelled and still being billed

I called at the beginning of Feb/end of Jan to cancel my contract as I did not want to renew it due to the numerous problem that I had already experienced with Autopage. I was assured telephonically that the account would be cancelled, last payment would be 20 Feb and if i did not port the number that it would be cancelled at the end of Feb. Come March and i received an invoice and was debited. When I called to get them t reverse this, they suddenly had no note of my cancellation, would have to re-cancel and the money would not be refunded. I have asked them to search for the phone call that is meant to be recorded. They say they will and that they will call me back, but as usual they NEVER call back. I am sick of having to fight them for my own money! Just find the recording and return my money. <br> <br> Additionally, the call centre waiting time is an absolute joke.
