Query: Poor Customer Service

Poor customer Service!When we bought this set a few years back it seemed very well built. In general, the set as a whole was really good. However, over time, one of our pans was losing it's nonstick. Since it had a 10 year warranty (which is why we bought the set), we called up the customer service. They were insistent we pay for the shipping and insurance (for that price we might as well buy a new pan...definitely not calphalon though).The eventually paid for all shipping costs for THEIR defective product. The representative was rather rude and obnoxious about it though. I have never seen such poor example of customer service from a supposed "reputable" company like calphalon. At least Kitchen Aid doesn't give you any hassle.When this set wears out...which I am sure it will....I will never go back to Calphalon, they are overrated and overpriced with terrible customer service.
