AOL is notorious for refusing to honor subscribers' cancellation requests, often employing such tactics as giving out fake cancellation numbers and keeping your account open after you call to cancel it. I just called to cancel my account tonight, and after being thoroughly hassled by the representative who could barely speak English, I finally got them to cancel my account- or so they say. I did not get a cancellation number, and I am concerned that my cancellation will not be honored. What can I do to ensure that I won't be billed again? Do I have to cancel my credit card? Can I call my credit card company and ask them to deny any more AOL charges?
