Auto purchased

NEVER trust this place. They lied to me many times. I purchased an SUV 3 months ago for my bother and the service engine light is on and they told me that they just finished doing the smog test and it will come out the service engine light after we drive 30 miles. The SUV actually has a problem where it will fail the smog test. They actually ask someone to pass the test and paid them more in order to pass to the DMV and the service engine never turned off and I tried to call them and they always make excuses and finally talked to the owner of MEGA Cars and told me that in order to fix the problem that I have to pay 800 bucks and they will fix it. I went back to Mega Cars the first month and there were other buyers who bought cars that they are also complaining regarding the car they purchased with problems. I'm already tired of calling them and I finally went to other auto shop on which I trusted and they told me that they can fix the problem easily and I only have to pay $350 on which the Mega Cars charging me for 800 bucks. WARNING!!!! DON'T EVER BUY CAR TO THIS PLACE!!!!
