Who called from 2124151548

Keep getting calls from this number when I answer no one is there. Try to call back and either get a busy signal or a recording that the number is no longer in service.

I'm getting calls from that number too.

I have received dozens of calls from this number....they had up

Sorry last comments were unclear.....I receive dozens of calls from this number for past 2 or 3 weeks.  When I answer, they hang up.

They keep calling. When I answered they just hang on the phone and didn't talk.
