I had a similar problem with my rebates, since the envelope I sent to the post office was damaged in shipment, which made me think all the packing lists, UPC's, etc., were all fsck'ed up by the USPS.
I called them up and asked to speak to someone in the rebate department about a week ago. Spoke with a woman named Mia, who looked up my information from the order numbers, did something on her end, and took care of the issue. She said it should take a week or so for them to be sent out.
Called them on the same phone # for the website 877 432 9675 .
They said I should have them sent out to me tomorrow when I checked with them this morning.
