Who called from 8018011801

Whoever it is has called me several times in the last few hours and when I finally answered and said hello, they hung up. Whoever it is needs to quit calling me.

They call me telling me I've received a grant and it's all mine if I pay the standard security fee of $3.87..

Whoever or whatever this number (801-801-1801) is connected with calls me daily.  Usually I am not home.  I have a personal policy to never answer the phone the has an area code with which I am not familiar.  This person/machine never leaves a message; so I don't know what company it is supposed to be.

This number has been calling me several times a for over a week now. I have not answered but they are calling at least 10 times a day.. I have no idea who they are!

I have received 4 calls today in regards to signing up for US Grants.

I have not signed anything looking for Grants.

When I aggressively confront him he studders  and hangs up.
