No offense, but it is not the store's responsibility to track your purchases.

Obviously, it wouldn't be worth the hassle to call up because of a lie. It happened and you happened to get the biggest a$$hole on the other end. Calling another store was the wise thing to do.

I once bought some shaver refill blades for a rotary norelco. The packaged had been carefully opened, resealed, and the blades were open, used and DIRTY! . I returned them to Kmart with no hassle. Now, the packages are quadruple riveted shut, heat sealed in plastic, and sealed with another plastic layer by Norelco. This must be a common problem.

I had my receipt.
