just be careful they dont delay it until they start billing you...
i just cancelled mine on my drive home

took me 12 minutes. wasn't as painless as i thought it would be, so i want to share with you guys how i did it
i was driving so i had to be on speakerphone (no headset for me

) after 5 minutes of screaming a bunch of yes's, no's, and my info into the speakerphone for their stupid automated lady in my car like a lunatic (they cant even catch my phone #... must be static on cell phone) i finally got to a person, who tries to be friendly with me and keep saying "awesome" (i'd kill him if he says awesome again)
he first asked me if i have broadband, i said yes. so he asked me why i cancel. I told him, I already have AOL (which i do have BYOA TCPIP for 5 bucks a month when i signed up back in 199?) and i opened a second one for my family. he said "awesome" i was like wtf at this point how awesome is it that he has this job. anyhow I verified my info and then I told him to verify the account he's cancelling, so he doesn't cancel the account i wanna keep. after he put me on hold for another 2 minutes. it's cancelled. the whole process, as the timer reported on my cell phone, was 12 minutes.
now i have to wait for written confirmation, which he said will take less than a week. and I can use my AOL until the 24th of this month... whatever.
so to all those of you going to cancel, just tell them you have another account already... they wont ask you for that account. and you can tell them BS like "that account's under my gf/bf/dad/mom/dog's name"
