Lowe's Rebate for delivery charge a scam Tampa Florida

I bought a refrigerator at Lowe's and wasn't told until I got to the register that I had to pay for the delivery fee (it was supposed to be free). I was told if I sent the receipt to Lowe's Rebates, Dept. 5768-112, 751211, El Paso, TX 88575-1211 I would receive the delivery charge back $79.00. I copied the receipt and sent it certified mail. I got the card back with Lowe's signature dated 1/9/09. I just got on line to check the status because I was supposed to receive it in 6 weeks. The site said there was something wrong with the receipt and I should resubmit it. There was NOTHING wrong with the receipt and I have been through these rebates scams before (Dell) and had to fight to get paid. I am going to send it again certified mail and that will make me out about $10 for mailing and the delivery charge with no guarantee they won't find problems again.
