Panda Security false rebates noted , Internet

I recently purchased a panda security internet virus packet from Office depot in Newark DE I submitted a rebate refund for $20 and WAS informed it was received and called several times and was told it was being processed, In July I called and was told that the check would be mailed out on 7/24 it was never received. I called Panda on 8/21 and inquired and they had in their files my rebate from 2009 but denied having my new status alleging they didn't have my information which I found strange they had prior. I believe they destroyed my information for the new rebate and it appears there is now no rebate to be forwarded.
