Query: Damn door

Bought this almost two years ago, within months the door wouldn't close. Who's paying to ship the defective units back? Me, but whatever. Cuisinart replaced it and assured me they'd fixed the door issue. Within months the door on the new unit stopped working. So I call Cuisinart and they give me a hard time, a lot of attitude, and can't assure me that the problem has been fixed. They offer me a new TOB-50, a new TOB-30 (the one that so many users here have said dies after a short time) or a letter of credit. Who pays to ship the defective unit back? Me, of course. And then I have a credit with Cuisinart. Do I want to keep doing business with them? Not so much, but I also don't feel like throwing it away. Aggravating. And I'd been fan of their products in the past. I assume their customer service people are getting hammered. How else to explain all that 'tude?
