Query: pitting in first year

My set is a year old and several pans already have severe pitting on the inside bottom. I never used metal utensils or put in the dishwasher. I called customer service and was told it was only a limited warranty and I had to pay to ship it to them and include $7 per pan for return shipping with no guarantee they would even replace them.I definitely would not recommend these.
