Ray-Ban Glasses Defects and Unsatisfactory Service

I recently bought a pair of Ray-Ban glasses from your store, hoping that the quality would live up to the brand's reputation. Regrettably, I was greatly let down. Even though the glasses were quite expensive, they ended up breaking before the warranty was up. When I brought them to your Gaziantep Gazimuhtar Atasun store because they had become loose, I was informed that it was my fault. Even though I hardly used the glasses and took good care of them, they ended up cracking from the frame. Once again, your service team blamed it on "user error." I hadn't even noticed any major harm. Don't high-quality glasses withstand regular use? I put a lot of money into these glasses, but I ended up feeling really disappointed. I kindly request you to reconsider your position and offer improved assistance to customers, such as myself, who have been disappointed by your service.
