30 south sunglasses issues still not resolved!

Last year, I acquired the 30 South Sunglasses Durban sunglasses, and after 4 weeks, I found that the lens was deteriorating away and notified the company 'as the policy specifies Lifetime warranty in frames and glasses and still, and the company has not addressed my problem. Why False promote if the company's policies are not followed, I may have purchased another brand believing that I would help support local products, WILL NOT RECOMMEND THERE PRODUCTS!
