Bridgestone Tyres India — Quality of tyre purchased is not good

I have bought 5 tyres from one of your dealers near my place on the 30th of April 2018. I have hardly used the tyres. Recently I could see a cut mark on one of the tyres used. When I enquired about this with my mechanics they informed me that this is definitely a matter of quality of tyre given. When I enquired about this with the dealer with whom I have purchased it, I didn't get a proper response and I was treated rudely. I would like to register a complaint about the quality of the product they have given to me. Kindly please enquire and provide a replacement for the bad quality product which the dealer has given.
