Volkswagen India — Very poor paint Quality by Volkswagen dealership and no support from Volkswagen customer care

Hi, My vehicle is a 2013 Volkswagen Polo highline registration number is AS 01 BG 6344. I got my car painted at a Volkswagen Guwahati on Feb 9 2023 and I paid roughly around 75000 for the same. The paint quality was so bad that it had more than 40 dust particles on bonnet, the door lines and dents were not aligned properly and also the paint has started to peel off on its own. So I raised a complaint on 18 March, 2023 on the Volkswagen toll free number. And that time I was informed that Volkswagen dealership has closed and my issue would be resolved free of cost when the new dealership opens. Now when the new dealership opened, the new Volkswagen dealership is denying to do it free of cost as they did not commit the mistake of poor paint Quality and they are blaming the old volkswagen dealership which was owned by OSL Exclusive group.
So I informed this matter to Volkswagen customer support and every time I call them I get the same response that my issue is being reescalated and they would call me back with a resolution in 48 hour. But it has been 6 months since I raise a complaint with Volkswagen customer care but not a single call back was received by me nor did I get any resolution.
