Who called from 9377633343

I have received several calls from (937) 763-3343 out of Hillsboro, OH. They don't leave a message.

They call. I answer they hang up.

They keep calling. The first time they said something . the second time nothing to day

just hold down your finger on the callers number and it will allow you to block number.

Many, many calls.  Have asked 2ce to be removed.  They (another country, with an accent) state that I'm entitled to a government grant of $8,000 that does not charge interest or need to be repaid.  Challenge them and they hang up and the number can't be re-dialed.  Anybody know how to get rid of them?
