Vision Express — power sunglass frame broke without usage. worst quality

Address: 500090

Worst quality of sunglasses. I have purchased power sunglasses from vision express hyderabad forum mall. Have not used the sunglasses and one day when i opened the box the sunglass frame seems broken at one edge which cannot be used. Couldn't get the replacement from nizampet branch as they have asked me to visit the forum branch. Reached out to them and they have replaced the frame with a new one. When i have asked them the reason for such damage they said its because of melting the glass to fit in the frame and have assured me this incident would not repeat. To my shock here comes the same problem again when i wanted to use these glasses while travelling to a tour as i do not use them regularly.
It's just waste of money.
