Gangar Eyenation — Photochromic glass quality

I had bought 2 photochromic frames/ glasses one for my daughter and one for myself from pimple saudagar branch pune. The quality of photochromic glass is very bad and even in the summer there is no cooling effect and no transition as mentioned at the time of purchase of frame
The glass provided are of gangar own brand. We paid higher amount as compared to market rate and other competitors assuming we will get good quality. But we are highly dis satisfied with the product.
The owner founder Mr gangar is making money by selling low quality product at sky high prices..The product which is [protected]@ Rs. 1000 he is selling 3 times higher rates.
Based on our experience we feels that we are cheated and must get the full refund of amount from Gangar eye nation.
Take necessary action against the company and provide me with justice
