I have received XXXX phone calls from a XXXX XXXX XXXX at XXXX XXXX. In my XXXX dealing with XXXX XXXX he claimed that I had a debt on an XXXX credit card in the amount of {$3000.00}. I informed him that I had just pulled my credit days prior to his phone call for a mortgage and that credit card shows a zero balance and has been cancelled. He told me that the debt is mine and must be paid. I asked him what his address was so that I could send a verification of debt letter. He refused to give me his address claiming I could be some sort of " whacko '' and " how did he know I was n't going to send him some sort of threatening mail. '' I assured him that all I wanted was his address. He refused. That 's when he told me he would sue me and file a lawsuit in the state of XXXX. He 's in XXXX. I then said if you ca n't supply me your address, I ca n't work with you. He called back yesterday claiming my drivers license would be suspended and that my wages would be garnished. I again asked for his address.. he again refused to give it to me. He then called back and left a voice mail stating he would settle the debt for {$2000.00}. He again threatened a law suit in the voice mail. Then on XXXX XXXX at XXXX XXXX XXXX XXXX called again threatening to file a lawsuit on Monday if I did not pay him his money.
