Query: Worst wok I've ever used!

After the very first batch of stir fry, the non-stick coating began peeling off the bottom of the pan! I had an old west bend for ten years and though it became warped after many years of use, the non-stick remained good. I think there was something very defective here. I am still waiting for a refund from Salton.
