Brake repair service near West Covina, CA

Brought my vehicle in to have it diagnosed because it didn't pass the smog test. In short, dropped my vehicle off at 9:30 am, he didn't have it ready for me until after 4 pm. Billed me over $100 for 1.2 hours of work. When I picked my vehicle up, the drivers side window was stuck half way down. Couldn't roll it all the way up or all the way down. When I asked the mechanic if he could take a look at he told me he couldn't look at it because he had "other" customers and I would have to either leave it or bring it back in the morning. Told him I needed my vehicle for work. That didn't matter to him. Ended up taking my vehicle to a friends who was able to remove the door panel and fix the problem in about 30 minutes. In summary, they had my vehicle for 7 hours for a diagnostics check that took a little over an hour, was charged over $100 for that diagnostic check and then wouldn't take 30 minutes of their precious time to take a look at a problem that happened while they had the vehicle.
