For the past few days now, I have been receiving threatening phone calls from someone in Seattle Washington that claims to be a collection agency. They first called my father stating that there was fraudulent activity linked to me and my SSN. When I called the number, they stated that I had taken out an online payday loan in 8/11. They couldn't tell me who it was through or the amount. The lady threatened to have papers served to me at my job or my house and have me thrown in jail. I received calls at my job stating that I am having charges filed against me and paperwork is being sent to my county of residence and I have to appear in court and I need a defense attorney, etc. I told the first lady I spoke with that I didn't take out any online payday loan. What can I do to stop this harassment and the phone calls?
