I got calls from these people for quite a while. I never answered the phone and they never left messages, I just know from googling the phone number. Eventually they sent a letter threatening collections to me. I sent a DV to them and they went away. I found out from googling the number that whoever these people are, they apparently bought a bunch of EXTREMELY old BMG accounts and are now trying to collect whatever they can. They shouldn't be able to legally add a collection to your report since it is probably way outside the amount of time they can report, however, that never stopped a CA. Ignore the calls, but if they send you anything in writing, DV it immediately.
