Good luck, they'll never let you cancel.
AOL: Hello and thank you for calling AOL customer care, how may I help you?
You: I'd like to cancel my AOL account.
AOL: I'm sorry to hear that Mr. Jones. Are you sure you want to cancel? We are prepared to offer you a free month.
You: No thank you.
AOL: Mr Jones, what if were to offer you two months free?
You: No.
AOL: Mr Jones, We normally don't offer this to our customers but I will give you 3 months free if you stay with AOL.
You: That's very generous but no.
AOL: Mr Jones, Is there anything we can do to keep you with AOL.
You: No.
AOL: Very well Mr Jones, are you familiar with the AOL wall of shame?
You: er, no I'm not.
AOL: The AOL wall of shame is a public website where we post the browsing habits of our former members. I show you've made a few visits to chickwithdicks.com.
You: What?!? I've never been to such a site!
AOL: I show you last visited this site on Saturday at 11:34pm
You: I guess I'll keep my service after all.
AOL: Thank you for calling Mr Jones.
