PTron — Delivering faulty products and not co operating with customer

Address:

Plot No. 2, 8-2-703/2/B Road Number 12, Banjara Hills Hyderabad, Telangana - 500034.

I had ordered one of their products .It was a TWS. It worked great had no complaints about it for 15-20 days I think so and then after 21 days it's charging case isn't charging anymore .If I couldn't charge it's case then how am I suppose to use those buds when they run out of charge completely.
So now I am unable to use them and it's in warranty and not getting response up to what I expected from a good company.
