United Nations Legal Department Fraudulently representing themselves as attorneys and debt collection, threatening phone calls Hudson, Florida

This place represents themselves as United Nations Legal Department and refuses to give their address or accurate phone number and they call more than one time a day, with veiled threats including having the police come to your door, threatening jail and court action.  The longer you stay on the phone with them to try to inquire about what company they are representing, the more abusive they become, when I read a previous rip off report to them, they became even more abusive threatening me with serving papers against me, etc.  It is completely against the Fair Debt Collections Practices Act and should be investigaged for a class action lawsuit for fraudulently representing themselves as attorneys.
