I got a postcard from PNY last week on a $15 memory rebate that stated that I had submitted an incorrect UPC. I called the provided number and eventually got a CSR. I told them that I had sent the only UPC on the package. They then asked me if I had a copy of the UPC, which I replied that I didn't, but I could send them a scan of the rest of the package, which has a nice gaping hole where the UPC was. They replied that they would need to verify the UPC code, because 'most likely whoever was entering the data from my submission entered a number wrong.' I then argued with the guy, asking 'why it was my job to provide further documentation to clear up a data entry error on their part, and why they couldn't just look at the materials I had originally submitted.' After several minutes on hold, I was told that they would go ahead and send the rebate.
I'm guessing that the place where you send the rebates enters information into a database, which gets forwarded to the company issuing the rebate. That may explain why they couldn't just look at my original submission. However, even if it was a data entry issue, wouldn't only 1 or 2 numbers be off? I realize it involves making an 'executive decision', but maybe they could just 'assume' that if the other 10 or 11 numbers matched, then maybe I did actually submit the correct UPC.
At any rate, I think a lot of companies do these sorts of things to minimize rebate payments. I know only a few people ever bother with sending in rebates versus the number of people who buy the product, so they save money that way. Then, I'm sure they can catch a certain number of submissions with technicalities, and they'll deny those as well. However, when you do everything right and still get denied, it makes you wonder what's going on. It's almost as though they are applying the 'guilty until innocent' approach.
I've had other rebates before that had similar issues. Warner Bros. free DVD mail-in offers come to mind. They use a company called Gage Marketing, who is notorious for denying offers for stupid reasons.
