Query: doesn't last, poor customer service

This was a fantastic toaster oven for three months, and then the door stopped closing completely, which I see is happening to other reviewers as well. Customer service is terrible - just got our replacement in the mail (after spending $20 to ship the broken one) and the replacement is dented and damaged in transit - shipped in a tiny box with no padding. Tried to call them and can't even leave a message to get help - their voice mail is full!
