It's for less than $ 650 , and he claims he has my soc . sec # , which he couldn't have obtained legally . He says he can put a lien on my bank account and take my assets . I don't believe it , but I don't know what kind of underhanded things recovery guys can do . But he won't show proof of a judgment against me , and I know that this judgment he claims he has does not exist . Are these empty threats ? How mush damage can be done with a SS # and possibly an illegal or no judgment ? He doesn't have my current address & doesn't know what state I'm in yet , but says he will find me . Is this possible ?
