Who called from 2132924507

Answered but no words were spoken other than me saying "hello" multiple times.

Received a call this evening and yesterday evening at the same time. No message the first time, I answered today and there was no one on the other line. I attempted to call it back but I get a message saying the person I am calling is not accepting calls at this time.

Call my cell phone repeatedly.  Leaves no message.

3rd telemarketer from LA in a row the last 3 days. I keep blocking their numbers, but they're using different ones. Beware people. They're in overdrive apparently. Don't answer, just block.

Keep calling, don't answer unknown, leave no voicemail.
Blocked the number but still calling.  Annoying!
