Just called me being very rude and demand

So did I and I'm about to report them to Feds so please let who ever this number is to that if they contact me again I will persecute them to the fullest extent of the law. Leave me alone

They have been calling me morning, noon, and night since around the 10th

I got 2 calls today from this number anybody know who or what it is.

They say they are from the US federal treasury n you won 7000 don't have to pay it back.  It's bunch of bull [***]
