In my old apartment one of my housemates broke a window. Our apartment manager referred us to Anderson Glass Company, wihch is supposed to be the best and the oldest in Davis, CA.
What had turned out was that the service was expensive and mediocre. The workman who came to measure our window measured the window incorrectly. He took out our old window, breaking it, and then tried fitting in the new one. The new one, however, did not fit. He had to go back to the main store and order a new one.
He took two trips instead of the one that it really should have taken, and charged us double for labor. I complained to the manager, and requested for a discount because we were waiting so long for a window to be fixed, and also being charged double for labor... but she had said that she couldn't because they were already at a loss for ordering a window that can't be used. In this way, she was putting some blame onto me.
Anderson Glass may be the oldest and the best, but when it came to fixing our window, it wasn't the best. They made mistakes (but to be err is innate to humans) and their customer service wasn't very good.
