Should've gone to Sunglass Hut not to Specsavers

I purchased a pair of Under Armour sunglasses with greenish/lime lenses from Specsavers Walmer Park on 26 October 2025. Within just a few days, I noticed a mark or discoloration developing on the left lens. I tried cleaning it, but it did not come off. On the seventh day, I took the glasses back to the store. I was assisted by a very helpful lady named Kim, who took pictures and said she would send them to her manager (who was on study leave at the time). Later, I was told to bring the glasses in again so they could be sent to the supplier for assessment. I have now been informed that the supplier claims the damage is “not their fault,” and that Specsavers can only offer me a discount on new lenses—which would not even match the original color. This outcome is extremely disappointing and unfair, as the defect appeared within days of purchase and was clearly not due to mishandling on my part. What frustrates me even more is the inconvenience and time wasted—I had to drive there three times, and I live quite far from Walmer Park. The travel costs and effort I’ve put in almost equal the price of a new pair of sunglasses. I have been a loyal Specsavers customer for years, but this experience has truly left me feeling undermined and unappreciated. The overall handling of my issue felt condescending, and I believe I should have been treated with more respect and understanding, especially as the product became defective so soon after purchase. I am very disappointed and regret not having gone to Sunglass Hut, where I feel I would have been valued as a customer.
