Query: Poor Quality, Poor Customer Service

I have had the All-Clad slow cooker for about a year, having used it only about 8-10 times. Unfortunately I did not save the receipt, for it no longer cooks the food. It did only a mediocre job at first, and now does not cook the food at all. All-Clad will do nothing without a receipt. The product is made in China (they told me that all their electric products are made in China), and they apparently do not exercise good quality control. I have had several cheaper slow cookers over the years which have done a better job at cooking the food and have lasted a lot longer. I do not intend to purchase All-Clad products in the future.
