Original English Text: My 2017 camry got a check engine light and my car had a strong odor of gasoline after service closed, I asked the receptionist if there was anyway they could get me a rental and she said they were closed so she recommended me to come in bright and early at 7am on monday so they could look at my car so I told her I left for work at 6am cause I work in north scottsdale so I told her I didn't not want to drive my car to scottsdale and back because I was afraid my car would blow up or something from the strong odor of gasoline and she put me on hold to talk to a manager. When she came back on the phone she said her manager was going to get a hold of the rental manager to see if someone could come in tomorrow ( today now ) to get me a rental and I left my name and number and no one has reached out to me. It's great to know they don't care if their customer's car blows up on the freeway cause it's not a sale ! Thanks avondale toyota you guys rock ! ! ! the dealership I work at teaches their receptionist to hand out rentals cause they know stuff like this happens, you guys might want to look into that !

Original English Text: I have used this company twice. The first time they were great. We spent over 5,000 for installation of a new ac unit on a rental property. Since they did an excellent job, we had them do a redesign of ac system in our home to improve the cooling in our house. It was one of the most frustrating customer service experiences I've had with a contractor in the 25 years I have lived in phoenix. They didn't complete the job in the time frame they promised. They damaged the faux ceiling in the kitchen, they drilled holes and didn't repair them in the bedroom. They left marks on the ceiling in the living room, where they marked to cut a hole and then didn't. Which told me they installers were not skilled or professional. After waiting for 2 months for them to repair the mistake in the kitchen, we gave up and paid to have it repaired. I heard a lot of promises, no solution. I would never use this contractor again.

Original English Text: There's so many choices of food in Las Vegas. Don't choose this place. It is no exaggeration that mcdonalds and arby's have better hash browns, eggs, and bacon. Missed items in the dishes we ordered. All around disappointment to the las vegas allure.
