Walgreen's Easy Saver Problem

I checked the staus of my rebate claims online this morning and there was a problem. The computer system apparently didn't recognize the RFN of one of the receipts. That's $4.00 and the $0.40 extra for putting it on a card that might not be back on my card! I called the number listed in the FAQ section and the guy told me that the call center and the automated center are on different systems. I was told to remove that receipt and claim the rest and then in a minimum of 15 days call back when the information should be in the call center's computers. Anyone else had this happen?
