Who called from 2012839712

Called and heard the option menu:
1. Connect to customer service
2. Request to be put on a "do not call" list
3. Leave a voice message

Guess which one i chose?

Did not leave a message and I did not answer the call.

Called my brand new cell number, didnt answer

I just got this new phone and activated it today and in less than an hour got a call from this number!

Called me just a few minutes ago and didn't leave a message as well. Has anyone called back that number?
