Paint quality bad

I bought a new car in April 2019. I am very much dispointed about Paint quality. Gallant red color is good but paint job done by MSIL was not good. How the quality check team pass the car. Dots and some un matched rough areas I was found on my car. Remaining everything was fine. My car was ZXi AMT, mileage is present 15 in local and 18 in high way. With a/c. Interior good. But some sounds coming at doors plastic. Cabin Space good, ac good, but steering I feel some where tight. While auto shifted gears feel some jerks but negligible. I had a bad experience with dealer, he cheated me for about 11,000/- by forced accessories after my payment. And also for his acheiving monthly targets car purchase date is showed 10 days before.
