UAC Car hop vallejo,california ripping me off vallejo, California

I bought a car on December 31st something to start my new year with. unfortunately that has all changed sinceI have gotten the car. it had not ran properly. I also had them note this on the contract since dec 31st. it is now thr 22nd of jan I have taken my car to the shop three times and have been without a car. they refuse to give me another car and when I call they tell me there is not much I can do. they have taken out the car note for this car on time but have yet to fix my car at all. im stuck with paying a car note missing work and still have no car. what a great way to run a business. sell lemons to the people trying to rebuild their credit
