Poorvika Mobiles — Realme buds wireless

I have purchased the realme buds wireless from poorvika mobiles dharmapuri.when purchasing they informed me that this product has one year warranty so that one I have purchased by giving Rs.2, 000/-

Now that product gets some problem as it is not damaged externally and no water damage, the problem is internally manufacturing fault only, they analyze those problem and finally conclusion they are simply saying the warranty period closed the period is only for 6months irresponsible support I had in that showroom, while purchase they are saying once then after getting some problem they are saying irresponsible reasons and in the store no one is caring about my voice...

As I too in the sales dept concern I have let out from the store aggressively.
Just I have attached the invoice copy do the needful as soon as possible because without that I could able to manage my field works...
