AOL
Can't cancel contract

I have cancelled my contract with AOL approx 6 months ago as we were moving home.

I have phone, emailed and written to them but they are still

drawing £9.99 per month on my credit card.

I have been given a cancellation no. but it made no difference. The bank say they cannot cancel the charges. Even if I cancel the card and take out another the charge will just be transferred. How the hell do we get rid of AOL!!
