This number called me today, I answered. They actually talked; said they were with the U.S. Grant department and I was selected for a $9700 tax free grant because I don't have a criminal record and have always paid my taxes on time.
Received a call today from this number and when I asked how do I get my phone number taken off of their call list, his response was "oh it's simple, you just smash your phone"
Called me today, asking me for my mother (who lives in a different state). When I told them this, and asked to be removed from their list, he told me that he knows where I live and said he could just 'come by whenever he wants to talk to me'. He then asked me if I live alone. When I asked for the name of the company, he said it was the Federal Government and hung up.
