Poor afters ales service from Luxury Brand Dolce & Gabbana

purchased a D & G handbag from the South African store in June 2018. Since I own many other luxury brands I only used this bag not more than 5 times until March 2021. I recently removed the bag from the D & G cover to be used and noticed that the zips and lock are changing colour. I called the store the next day and they said it should not change colour & should bring it in. My bag is in pristine condition by the way. My husband dropped of the bag and the manager mentioned oxidization and informed my husband he will send it to the Head Office for a review. I received a call today to be told that everybodies body is different and mine might be to acidic that caused the oxidization and they cannot do anything and with the cost to repair the zip it would not be feasible. So basically my body is not too acidic for a Versace, Louis Vuitton, Gucci or a Coach handbag only for a D & G handbag. This is so disappointing and I will never support a brand like this again. Please reconsider your decision to support this brand as we pay an arm and a leg and get poor quality zips, terrible customer service and after sales service.

Please becareful guys.
