Who called from 2132575233

Received a call from this number at 11:03am on 5/1/15. I did not answer, and they didn't leave a voicemail. When I tried to call it back, I got the following:

Verizon Wireless... the number you called has either been changed or disconnected, or is no longer in service..."

call to my cell phone - nobody there - autohangup

Repeated unsolicited, unwanted calls for many months.

Called.  Left no message. Called the number.  Number "disconnected or not in service".
