XXXX XXXX XXXX ( also known as XXXX per their messages ) has been calling harrassing me for weeks on a debt that is not valid. Claiming that in 2009 I walked into a physical payday store called XXXX XXXX XXXX ( which in my state there is no such thing ) and took out a loan and deposited it into a bank account that I had closed years before 2009. I have received no formal debt validation letter so that I could dispute this. When I asked for a debt validation letter she said they do not send out that information, etc. I explained that this debt is not valid and to stop calling me. She started to threaten that I would be served papers at my place of employment and/or home. I asked for their physical address and formal name of company, she would not provide me with any of that information. They lady would not let me speak, she was extremely rude. Even after requesting the calls to stop, they continue to call my home, cell phone, and work number.
