Unceasing contacts from XXXX different 'collection agencies ', from XXXX different phone numbers. Calling my office ( number provided ), my cell, have called my spouse at work, my inlaws on home and cell, my father in New Yourk, and sister-in-law in New York. They identify themselves, but refuse to say who they are calling on behalf of unless I affirmatively identify myself with SS #, date of birth, or some other 'personal ' information. Tried once to get them to stop after they got to my wife at work, but insisted on my affirmative identification in order to 'change my contact information '. Calls from second number/company seeking 'employment verification ' for me. The call to my father got a little further, as he and I have the same name ... so when asked, he 'identified ' himslf by name and they did tell him what it was for and for how much. My office assistant has to field these calls daily, and that is embarassing as well.
