I bought a car from them and within 2 days there were warning lights going off

I bought a car from them and within 2 days there were warning lights going off. I took it in for repairs as it’s still under warranty. Iv been waiting for over a week. They keep giving me the run around. I just want my car fixed. It should’ve have went through quality checks prior but they failed to do that. This is the worst horrible experience Iv ever had and Iv purchased quite a few cars in my life. I was suppose to collect my car 3 days ago and they are still saying “we need to test run it”.
