Rang twice and hung up.  At 7:48 in the morning on my cell.

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.

Rang once and left no message on my cell at 7:00 am.

Rang for 1 second at 8:34 PM.  Thanks to this website, I will not call back.
