It happen once to me when I send in the rebate for Linksys 4 ports USB hub. I called or email (don't remember) them up with the info they provide on the post card. A girl answered my call/email and got everything straight out. A sweet girl. 
She told me sometime company hires outside vendor to do the rebates. Sometime other vendor's employee just grab one UPC from here and grad another receipt from there and make up their own rebate, so they can have rebate money for themself. And o'course we are the one who suffer. :|
