First of all, they give a window of 8am-5pm so you have to take off from work to be there. Then it always takes 2 visits to fix (1 to diagnose and order parts and the other to install). Finally for this issue with my fridge they rescheduled FOUR times! Thats 4 times I took off from work and then got a call "sorry no technicians available".
Once someone does show up they tend to be friendly and competent but the scheduling office is far from being so.
