The call started out half human half automated and it rambled on about it being XXXX services and stated that they needed to hear from me or my attorney by today and to refer to file # XXXX. The call came from XXXX. During the call it gave me the option to call back or speak to a representative by pressing XXXX. I elected to speak to a representative. A man named XXXX went on to state that I have an outstanding payday loan that was for {$2500.00} that I never paid back. He states that if I do n't pay they will have the sheriff serve me with documentation to appear in court either at my home or place of employment. I advised him that although he has some of my information not all of that information is mine. He became very nasty calling me a liar. I then advised him that I am not paying a debt that I do not owe and is not mine. I requested that he mail information from the original debt to me, he stated that I had already gotten this information years ago and ignored it. I then asked him to email it and he stated that they do n't send emails. He then gave banking information that I no longer have because I had an issue with payments being taken out for a company that I did n't know. He then told me that he has my SSN and that in the end I will have to pay up or go to jail. When I asked about being sent a noticed by his company due to being taken to court and that I never got it, he stated that it was my problem not his. I told him that I ca n't dispute a debt if I do n't have validation of the debt and I do n't have anything in writing.
