I'm on AOL and have heard some similar stories. Maybe not so much a spoof! A workmate of mine cancelled his AOL account but still they took his monthly payments through his credit card. His bank are now dealing with it but so far its been twelve months and still not resolved! Being forewarned is always useful and if ever I want to cancel with AOL I'll involve my credit card company at the date of cancellation.
I had a very similar experience to Rdave13's friend. When my family moved back from the USA it took ages to get AOL to stop taking monthly debits from the c/c account. I tried e-mails, letters, faxes, the lot.
