This is a debt collector scam- they will contact everyone that you have listed in the debt and try to scare them into getting you to contact them and/or into giving banking information. Do not let them do this. Report them immediately to the BBB and also to your state attorney's office(the section that deals with debt collectors). These people are relentless so if you have an attorney I would have them contact them back for you. Hope this helps.
