Harassing me multiple times a day then hanging up

Harassing male caller multiple times a day then hanging up

This number does not stop! Second day, every 10 minutes, no message and busy when you dial.  WTF

Its this indian guy that calls me every like 6 months. He knows my name and jokes around that he meet me in Pennselvania even though I have never been there in my life. It's rgoddamn creepy because he found me on faceboook I beleive by phone number and knew all my inoformation. He then kept saying I was pretty and laughed with some of his scammer callegues. It's really irritaing because if I dont answer he calls 3 times more. Pisses me off. But at least he only calls once every six months. Sometimes when I pick up he doesnt say anyhting and hangs up. Also this time at least theirs a number before he used to call me in an blocked call. I only answer because it's quite amusing what people think they know because of your social media.

Kept calling multiple times a day telling me about a grant when i asked what this was part of and how he got my information kept beating around the bush saying it was some grant department and they wouldn't ask for any information also said they would coach me on what to say to receive this "grant" obvious scam i told him i didn't want the money and to stop calling
