Debt ??

Check your credit report. If an account is sold off, there should be a JDB listed with approx the same amount, and the OC tradeline should have a zero balance and say "sold to another lender".

Usually if the Original Creditor charges it off they will sell it to a Junk Debt Buyer who will act as if they own the debt now. They will start with harrassing calls and letters, if they can't get anywhere with you then they will try to collect through the courts (the new collection agency) for the balance plus all kinds of interests, et cetera.

If you think that your debt has been sold, send a DV letter to the company if you are not sure or recognize them.
