Received a phone call this morning from ARA XXXX claiming to be a law firm ( XXXX ). Claimed I owed a line of credit to XXXX XXXX XXXX for {$20000.00} from 1992 and that I needed to pay immediately or they would file a lawsuit with the XXXX XXXX Courts and the sheriff would be at my door with a summons. I told them I have never done business with XXXX XXXX XXXX and have never had a line of credit. He said that it has showed up on my credit report for years and many attempts have been made to collect. I told him I have never seen this on my credit and I do not owe the money and that the statue of limitations has already passed. He said I must owe the money because I know of SOL and that he could make a deal with me to settle the debt if I paid now. I once again told him I did not owe the debt - he then processed to talk over me in a very threating manner saying that he was going to file the suit and the next time I hear from then it would be the sheriff at my front door - he then screaming some profanity at me and hang up. I am over XXXX and feel that this type of behavior is getting out of control especially with the senior population.
