This was the only company out of four appliance companies I called that actually answered their phone. The woman scheduling felt bad she couldn’t get me in sooner, and I thought it was nice she seemed concerned that I wouldn’t be satisfied with the appointment date. (It was fine, I’d already gone a few weeks without my dishwasher at that point.)
They gave a four hour appointment window and about halfway through it, I called to see when the repairman would be here. They were able to look up where he was on his day and let me know he had one more stop before me.
He arrived less than an hour later and went through my dishwasher thoroughly. Everything is fixed and he went on his way.
Hopefully I won’t need to call anytime soon, but I wouldn’t hesitate to call them again.
