This is most Likely a prank or scam. As i got a call too and when i called it back and asked what the lawsuit was over all i got was a guy saying do i want to hear about the details. I again asked a simple what was the lawsuit about, to see if money, property unpaid, student loans, or whatever he might say. This just made the guy mad and he proceeded to cuss at me and then hang up.
305 363 3424 is an IRS scam. David smith and Richard Lewis is who I spoke with, I asked him for his real name instead of his fake name and he said Abdul Ansari. I am reporting this to BBB.
