I've been contacted by this company and OH BOY.  The first time, I was informed that this was a legal office, NOT a debt collection agency.  I asked for a bill, so that I could contact my old insurance company and see what happened.  The agent said that it had been too long and they probably wouldn't be able to get that information.  They did, however, send me their own bill on their own "letterhead" which didn't give me any actual information.  After talking to a lawyer friend of mine, I sent them a letter that asked them to send me verification of the debt, aka a bill from the original owner of the debt.  I sent this letter by certified mail, and asked that they also send me the verification by certified mail.  I got the return receipt, and for a month, got no calls.  Now, it's January, and they've started calling.  I've been keeping a log of when they call, and the moment they get past the "This is David Reitman calling to collect a debt," I simply say that they need to send verification of the debt by certified mail, and until then, they need to stop contacting me, and then hang up.  They've gotten pissy with me, and also offered to "make me a deal," but I've yet to see legal proof that I owe them money.
