I received 3 calls in a row and no messages. I called back with my number blocked and the recording advised that I'd recently visited one of their affiliate websites, and I was eligible to receive a $100 rebate card at popular stores like Walmart, Best Buy, Home Depot, etc. Then it gave the option of being connected to the rebate center or pressing "2" to be added to the "do not call" list.
I get a call from this number several times a day everyday. It needs to stop. They never ever leave a message. I'm going to report it to me cell provider so they can block it and research it to file a complaint for me.
