Supposed bill I owe from RJM Acqisitions LLC

:mad:I am a victim of ID Theft and RJM Acquisitions have been sending letters stating that I owe for some items that I supposedly requested from the original creditor that sold them the debt information, and I called them and talked to a customer service rep which told me that someone requested items in my name and items were sent to another address that belonged to my former spouse (that's who had to request items in my name and received the items through the mail from the original creditor) so they agreed to close the account and not send me no further bills and I still am receiving them stating I owe when I already talked to them and nothing was done, what can I do please help me.
