Query: BUY ANOTHER BRAND

I purchased 2 PNY 128MB compact flash on 11/27/02. One so far is working fine, the other one however is not. I can take pictures with my digital camera, and only about half of them turn out. I am also unable to down load them to my computer. I have tried for 3 days to contact PNY, I have left 2 messages, and still no return call. My problem is not only with the product, but also with the customer service. Unless I hear from them soon, I will cut my losses and buy another brand.
