Who called from 5137130720

This number has been trying to reach me on my cell phone for the last two weeks. I don't answer unknown numbers, and they never leave a message. I can't find any report online listing who this is...

This is AllState calling to sell you roadside assistance.

Second call came in today while I was away from my desk. I'll pick up next time and ask to be removed from their promotional call list (we have an AAA membership). If this persists, I might switch our insurance policy to another company.

Allstate Motor roadside assistance.

I called the number and it was a recording giving me their spiel. I did give me an option of pressing  3  to be added to their do not call list. After pressing 3 I was informed that I would be removed from their DNCL within 30 days. THIRTY DAYS?? How long can this possibly take??

I have spoken with them more than once and told them I was not interested. I keep getting calls anyway.
