Update: I called the OC (Comcast) and I was not successful in getting the account removed from the CRAs, even though they claimed they would call it back from the CA.    I recently wrote to the CRAs and included it in my 1-2 punch letters, along with a few other accounts. I basically wrote that I never had any dealings with that CA and asked for proof that I had paid any money to that CA. I just looked and it's disappeared from all 3 CRAs.    Good luck all!
