US Legal Department called and harrassed me and my employer Clanton Alabama

 Guy caller called and stated his name, which i couldnt make out due to his strong non english speaking accent. May be from India, Afghan ?? He stated my name, and my full social security number, and said he was calling from US Legal Services and there is a claim against my name and SS #. He said if I do not call hime back w/in the hour or by tomorrow morning, he's going to send the cops and I "will be put behind the bars for 90 days detention". Whatta Muke. Now mind you this is all via voicemails as I didnt answer a number from Alabama that I didnt recognize. I took this all w/ a grain of salt as I'm not much worried about him or his made up bogus company. Until today I get a call from my boss saying this fruitcake has been calling my workplace/employer number and harassing them. He's demanding to speak w me and was cursing at everyone, very heated. I dont even work in the office, I am always out on the road. So I called the Pa State Police today to ask what I need or should do about this. The officer I spoke with said to just ignore it and let it go, as he said these guys arent even in the USA 1/2 the time altho their caller id says otherwise. He knows theyll never get caught or tracked down and prosecuted. Either way I really dont like him calling my place of emploment and acting a fool. So I guess I'll have to let my boss know they will need to either block that number/numbers and or call their local authorities to handle this matter on their end. Thanks for reading and listening.
