Go to your Attorney General website and file a Fair debt collection act complaint. Most claims are followed up on and usually settled. Now that you will have a 30+ mark on your credit report you will likely have to fight it somehow.

First you are dealing with call centers that are sub-contracted by the company to do the dirty work and most of these people are un-employable by any other means.

send me an email and I will give you a call tomorrow and tell you how to put them on the hook! I have a close friend that is a collection attorney and have learned a few tricks of the trade.

I have usefully banged a collection company hard for a friend and after dealing with them I sometimes help people out for "sport" just to send some Crap right back at em.
