So, Frontier is claiming I owe them $74.98, months after I cancelled the account.

I sent them a letter asking for an accounting of the amounts which lead to this total, with date for each, so I could verify that I actually owed it -- and their response has been to send it to a collection agency, CCS, who is (of course) reiterating the demand without providing any new information.

Does anyone know how to say "fsck off, I don't owe this" in legalese?
