A very dissapointed nd unhappy customer

I purchased a ring at American swiss Mall@Lebo Limpopo in April 2023. In August the 2 stones fell off. I reported the matter to their head office. They responded to my query, they asked me to bring the ring for quality assurance i did exactly that. After 3 weeks which yesterday i received a call from one of their consultant/store mamager telling me that the ring is back accirding to their report the atones are falling because of my neglegence. I really dont understand how can i neglect my ring within 3 weeks. The value of that ring was R4500. I sent another email with that report to their customer services but they said my query is being resolved i asked how a manager phoned me to tell me that maybe i hit something with my ring and the stones did not fall at once. Apparently there is nothing they can do i must pay to fix my ring. I am not happy at all. I need my money or they muat just fix my ring.

Thank you.
