Who called from 7046665108

Called my cell phone at 9:30 in the morning, didn't answer, no message.

Missed call at 4:39pm. Called my personal mobile number.

Called me on March 2, 2015. Did not leave a message and the call disconnects when I try to call back

Just received a call at 10:52 am from 704-666-5108. I called back and the message says, "This is Lisa from Reward Redemption. You have recently visited one of our websites and we would like to reward you with a $100 gift card"..blah blah. In short, its obviously a scam.
