Can you just send a certified or registered letter demanding that service be terminated, with correct authentication information, and then skip this process?
Maybe on a law firm's letterhead?
(OTOH, I love fucking with these people on the phone. "Why are you canceling service?" "Because God told me the Internet is evil; Because I decided meth|guns|tinfoil|etc. would be better use of my money; Because a court demands I not have contact with the Internet for the next 3 years as a term of my release.")
