Who called from 9722126493

This number has called several times over the past week. Always silence when I answer, then when I call back a recording says the code or number dialed is incorrect.

Keep calling. Left a strange message the first time. After several calls I answered.  When asked who it was they hung up.

Keeps calling me and there is complete silence when I answer. Quite annoying.

Called and stated they were from the Sheriff Coalition fund requesting donations. And when I asked how you get my # they paused then Hanged up.
