I don't see why two weeks is a "ridiculous amount of time to wait." A dishwasher is a luxury, regardless of how many people might claim to be unable to live without one. A fridge/freezer seems more important, possibly followed by the washer/dryer, since it'd cost you money to go to a laundromat.

Two weeks is the length of time it takes to wait. Would you be writing this letter of complaint if it wasn't under a warranty and a regular repair company had told you it'd be two weeks before someone could come out and look at it?
