Volkswagen car service centre suggestions

Hello all, I have a polo tsi. I need suggestions for getting my car serviced. It needs thorough inspection. The VW Noida, in sector 63is very poor at service quality. Most of the issues I mentioned were not fixed, and they ask you to go to a third party mechanic to get it fixed. Is there anyone apart from that in Noida? I need authorised VW workshops where the service quality is good Thank you in advance.
