I moved from XXXX XX/XX/XXXX to XXXX. I lived in XXXX from XX/XX/XXXX to XX/XX/XXXX. I had all of my services turned off at my old residence in Alabama after moving XX/XX/XXXX. XX/XX/XXXX, I was contacted by a debt collection agency Transworld Systems , Inc. stating they purchased debt from XXXX XXXX XXXX in the amount of {$160.00} that was dated from XX/XX/XXXX until XX/XX/XXXX. I explained that I did not live there during that time, as I moved to XXXX. They were rude and continued to harass me stating that this is my debt and I was obligated to pay. They began to call my cell phone incessantly and then found my home phone number and began to do the same. When I continued to insist that I did not owe the debt, they stated if I could prove I did not owe it, they would stop harassing me. So, I sent them proof that I had services in XXXX in the form of a letter from XXXX noting when I started service in XXXX and when that service ended, i.e. XX/XX/XXXX until XX/XX/XXXX. I thought that would stop the harassment, but it has not. They are now sending me letters stating that I needed to settle a debt I do not owe. The letter indicates that they are monitoring my credit to see when an inquiry is made. The letter uses intimidation tactics and states, " We hope that you are now in a better position to pay the above account ( s ). ". I do n't owe money to XXXX XXXX XXXX or Transworld, and I am not obligated to pay for services I did not receive. They are invading my privacy and utilizing my personal identifying information unlawfully by monitoring my credit actions and possibly lowering my credit worthiness by suggesting I am severely delinquent for a debt I do not owe. Your assistance in this matter is greatly appreciated. Please see the attached documentation.
