Did you apply for a grant? Because that's the only way to get one. The government doesn't just call random people to give them money. And if you DID apply for a grant, you wouldn't have to pay to receive it. These callers are just trying to scam you. Block and ignore their calls.
Literally all morning long have recieved a call from this number... 850-549-2981.... Finally I picked up, they asked for a " Deborah ". When I replied " this is she " I was disconnected form them !! ..... will this number Ever stop calling ?
