Rebate fraud

After I had submitted my Coopervision rebate info online and received a tracking number from them, I mailed the paper work, receipts, end panels, etc, and waited for the rebate to come, but I never received it. So I called their customer service line and they were able to look up the tracking number but told me they never got anything in the mail from me. : ( I'd even made copies of all the materials that I sent to the company, but since the deadline has passed, there was nothing they could do for me. What a waste of of my time. I'm so disappointed, and it makes me more upset to read that there are other disgruntled customers who didn't get their rebates either.
