Who called from 4084792673

This is the number I was given to call to talk about my 9000 grant... After the other scammer called me.

claims to be calling from the U.s. Treasury department.  She claims that the government is going to give me a free grant of $9000.00....to good to be true usually is.  she gave me a code and a number to call.  The fact that i have to call a separate number seems a bit fishy.  the number i was told to call was 408-479-2673

I have received the same call with the same message. Obviously a scam. Now I don't know how to get rid of them so that they won't call me again!
