I got the same thing.  Total bull__it.

I got a call from this number and right away the gentleman asked for me by my former last name. Then he stated saying there were charges against me for bank fraud. I was like "what are you even talking about?" then he tried to verify my identity by giving me my social. He asked me if that was right, i said "i don't even know who you are". he then transferred me to the "Warrant division". It just was more crap from there and the next guy i talked to started getting mean and trying to be intimidating. I called the county clerk and they have no pending cases against me... which i was pretty sure they wouldnt. It was all so dumb.
