Folks--NEVER PAY that collection agency.....at least, never pay them unless they validate the debt. I dealt with RJM myself before, on two occasions. Both times, they were trying to collect for Columbia house, when I never had a CH membership. Not only that, but the little info they were claiming to have put these so-called debts so far outside the statute of limitations I almost died laughing when they told me. Seriously--that really happened, I laughed all over them on that phone call.
GET THEM TO VALIDATE--do not pay them, dont agree to pay them, NOTHING until they validate. They are known for buying up junk debts that are beyond the statute or not at all documented. Force them to prove their case.
