Lenskart.com review: Broken spectacle frame due to poor soldering

I am writing to bring to your attention an issue with the spectacle frame I purchased from Lenskart. Unfortunately, the frame has broken, not due to any mishandling on my part, but because of what appears to be poor soldering at the joint.

The damage seems to be a result of weak structural integrity, and I believe this falls under a product quality issue rather than wear and tear. I have attached photos for your reference which clearly show the breakage.
