Who called from 2021000000

I received a call from this number. Actually, I've received multiple but finally just answered the phone. They said they were calling from Washington with a one time 1,000 grant opportunity for me. I just hung up because the man on the phone could barely speak English.

I just had a lady call and said I could get 10000

They just called me and threatened to come to my house and shoot me in the head they repeated my home address and everything
It was very scary

Several calls from this number in last 2 days...getting annoying!

Saying I qualify for a federal grant. The guy on the other end of the line doesn't speak very good English. Told him not to call me back .
