Ac and heating repair service near City Of Industry, 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.
