Do NOT deal with debt collectors over the phone! Make them send you bills in the mail with proper documentation, then confirm the debt with the original debtor, NOT the collection agency. This company is sketchy as heck in their business practices. I highly recommend using a call blocker to stop the calls, reporting them via FDCA online forms, then getting a copy of your credit report to make sure no false debts are being reported.
I answered the ringing phone only to be greeted by a recorded message stating the call could not be completed at this time. I called the 800 number listed by a previous poster.
I'm a female - got a call from them looking for a male by the same last name. Have no clue how they associated my address/cell-phone number with the guy they were looking for.
