I have been getting several calls from this number.  Called it back and got a recording that says they are Reward Redemption and that I had recently visited their website and they wanted to give me a gift card to various locations. If you wait until the end of the recording, they tell you to press 2 to be added to their "Do Not Call" list.

This is harassment almost every night about 11 pm the phone rings a guy says hello 2 times in crazy static and hangs up... I have received 6 of these calls
