Who called from 3368428233

This telephone number is legit.

Rang once, hung up. Looks like a spammer.

They called me - left a VM about not being a valid extension? Spam

They called me, and my number is already registered on the Do Not Call list.

Called my cell, left no message, called back and it was a automated message from "Kelly with Reward Resumptions," asking if I would like a $100 reward for popular stores like Best Buy, etc...
