Who called from 8104075331

Call came in this morning and I answered it.  Recorded message blah, blah, blah.  Another number blocked.

Just received a call from this number.  I didn't hear anything on the other end.  It hung up right away.

No message...........just empty space.  Yesterday got calls from a "Detroit" 313 area code number that I won a free Caribbean Vacation. This shows a  "Flint" 810 area code.   Looks like they're trolling for suckers back in Michigan again.

Another pointless phone call from another bogus number, didn't answer, no message.

Didnt answer,,,,,,,,,,,,,,,,,no message left
