unsolicited phone call, do not want

called six times with no answer on other end....on seventh call, said they are a law firm which made a wild claim,

Called me on my Cell phone. Did not leave a message. I tryed to call and got buessy signal. Found this info on enternet.

Caller keeps calling with my name and says he has my social security number and that this is my last chance to fix a personal matter for a payday loan which I have never taken out a payday loan ever in my life. Also states that they want to wish me luck with my lawsuit against me. Caller gets loud and rude on phone and keeps calling and calling and calling also knows my address. What can I do why does this caller know my address and personal information?

Shows up on the Caller ID as "Fort Worth, TX". Leaves no message.

said i owed them money from a 300.00 dollar loan.i have never gotten a loan before.said i was going to be arrested the next morning and taken directly to court in handcuffs.i new i did not get a loan because since my divorce my credit has gone down the drain,in other words no one would loan me money on my credit report.all that night i was worried and had a pretty sleepless worring about the police coming.they need to be stopped before they cause someones heart attack and they end up dyeing.there has to be something that can be done
