No Autopage Account yet I'm debited!

After ending my association with Autopage on 9 Jan 2015, I was debited at the end of Jan for a full month's use. I had to follow up and eventually was refunded. At the beginning of Feb I called as I had received another tax invoice for Feb, and was given a reference number and assured that I would not be debited again as I had no active contract. 28 Feb 2015, and I've just had a debit order run from my account for no reason and without any authority. Disgusted at Autopage's incompetence and lack of communication. I would like my money back ASAP.
