Who called from 3124653520

Got this call at 8 pm today. Caller ID showed "WIRELESS CALLER."  Left no message. Called it back and got a recording stating it was Verizon wireless national payment center. The recording wanted my ten digit Verizon number. I don't have or use Verizon.

Got a call at 9:25am. No one answered when I picked up... and no one answered when I called back

Just got a call from this number. Tried calling back. No answer..

Got a call at noon from this number.  Showed as Cell Phone IL on caller id.  No one responded when I picked up the call, no human, no robot.  I called the number back immediately and there was no answer.

Got this call on a pre-paid cell number that I don't give out.  Assumed it to be robot.  Didn't answer.
