I received a letter from a debt collector and there was a check for $70 included. It looks like a 100% legitimate check, in fact I know the routing number is correct because it's the same routing number for my bank account. Anyway, there's no conceivable way that they owe me money as I have not paid them anything. I think this is a ploy to get me to call them and ask about the check, to verify that they have a correct and current address for me, to get my banking information somehow, or to start an all new collection proceeding by claiming that the money was sent by mistake. Has anyone else gotten a similar letter/check from a debt collector?
