The caller spoke with a noticeable accent, and obviously part of a phone bank system, as there was a lot of background voice and other noises.  As I understand it, he said he was with an office dealing with claims.

I know they called my husband too saying they were going to give him 9,000

It's a scam-there is no money.

315987100 called me and said the I.r.s. had sent me 8500 dollars. I asked why and she said that I was selected to receive a free grant. She was obviously reading from a script because she lost her place twice. She had a foreign accent and gave me an 844 number to call with authorization code al123. I called the police station and they said that the irs. Will never call you! Don't call the 844 number. That is where they try and scam you
