You need to report this call to the FTC (Federal Trade Commission) - they are impersonating a government agency. https://www.ftccomplaintassistant.gov/#&panel1-1
Got a call from this number. They said I had a federal Grant. When I asked how much I was supposed to pay them for this so called Grant they stopped talking. After several hellos from me they started talk I'm not gibberish. It's a scam folks the federal government doesn't call you to tell you that you have gotten a grant
Just received same call as above, ID showed Unknown I was selected to receive same amount $7800.00. I didn't answer they left the message. Wish it were true, but that's too good to happen!
