Query: Poor customer service and poor baking

We have tried to use our breadmaker 3 times. After the first flop we called the customer service number. The person at the other end didn't seem to know much other than what other customers told him.The last loaf was not even done baking at the end of all of the cycles, so we put it in the oven. Of course the top had caved in during the process, but after baking it in our oven it did taste good. The first loaf we just threw away and the 2nd loaf was a bit doughy.Needless to say we are not happy. Our old Hitachi never gave us a problem.
