Who called from 2020147497

There is NO grant.  YOU would be asked to pay THEM in order to get something that does not exist.

they call me several times the only time anything was said by them was when i didnt answer and i was called a B*tch and a Fu*king Whôre and something else, this guy just hangs on the phone forever untill that day cause when he called after and i answered i said say something if your gonna leave messages like that

I have asked several times for my number to be removed from the calling list. Although I get hung up on each time I do!!

These are criminals, Melanie. You have to take evasive action and not answer their calls.
If you don't recognize the number calling you, let it go to voice mail or an answering machine.
Most scammers have their autodialers programmed to stop the call after 4 rings and thus they will not leave messages.
