Droid users- look into the free blocking app Mr. Number. You can set unknown calls to go directly to voicemail, auto pick up hang up, etc. it's really easy to use! It is only available on Android devices. iPhone users now have a blocking feature on the iPhone now.
Called mobile number, rang twice, hung up, left no message. Called back with *67 prefix. A recording of "Christie" gives some BS about visiting one of their affiliate websites and pressing 1 to get $100 rebate card. Never left my number, so it's a damnable lie. Perhaps they work for the current administration.
Pretty sure they got the number from Verizon Wireless, I went on to check my data detail and got prompted to enter a contest for a big screen TV for just 2 reward poaints, so did....and not long after I get a call from this number.
