Don't bother returning the missed call. Automated message prompting to press #1 for a $100 gift card. Someone with a heavy accent in a noisy call center answers. Typical scam.
Called at 12:06 pm to my cell phone, no voice mail - I called back - got an automated recording "Jamie at Reward Redemption, you recently visisted one of our affiliate website...." then the call disconnected
Phone rang for 1.5 seconds, no voicemail, upon calling back it's a computer trying to get you to claim "a free $100 gift card to a major retailer". I didn't try to claim the gift card.
