Consumer protection act

I have cancelled my service in June and my account has been debited today with the subscription. looking at the reviews i guess, i will go through the same pain all of you are experiencing. I have sent yellodata an email now to determine why my account was debited and not cancelled. i hope they can respond and refund me. Based on the reviews it seems if i do not get any assistance the best would be to go the consumer Ombudsman and report yellodata in terms of the consumer protection act. Yellodata please advise?
