call from us treasury department seems like a scam caller had a thick accent

I just receive a call from this number that said tell your son to be careful and I ask what is the name and they said tell him my name is nobody

Caller claimed his name is Austin and I was eligible for a grant.  Told him not interested and he said "f*** you, b****".

Called saying it was the us government. Told them we knew it's a scam and that we were going to call the police and she said do it then do it

Called me asked if I were around and I said "yeah who's this?" Then said my full name (first and last) followed by a F*** you then immediately hung up. Had a heavy jihadi accent. Called back, but this individual never picked up. DONT BE PLAYIN ON MY PHONE!
