Company claiming to be from check fraud division called and left messages on family members cell phone and stated they were trying to contact me. They have called my home number numerous times even 3 to 4 times in one day. When I called the number where a message states the company name as Hart, Lopez and Associates' check processing department, then it gives names of people with a number to press to reach them. I didn't leave any messages, but someone attempted to call me back stating they saw a missed call from my number. I gave them my name, but they could not pull me up without knowing who had called, but they were probably calling about a payday loan I had not paid.  I stated I did not have a name, but if they were calling about a debt they needed to send me a notice in writing with all of the information pertaining to the debt. I also informed them I did not make any arrangements over the phone without having received something verifying who they are and that it is a valid debt. She then stated that I signed away that right when I took out the loan and they did not have to provide that information in writing. I stated again I did not make arrangements on the phone without first receiving something in writing. She then became agitated and stated "I guess they can just come arrest you then" and hung up.
