Extreme Poor service delivery and quality!!!!

I am utterly disgusted in the service and quality we received from NWJ Moffet on Main, Port Elizabeth. We bought my engagement ring 18 December 2023. They said resizing should take about 2 days as my Fiancé was planning on proposing to me on Christmas. After continuously phoning and following up, we received my ring on the 24th of December. The 5th of January 2024, the one stone fell out. We took it back to the store for repairs as the ring is under guarantee. WE explicitly told them to check ALL stones as we don't want another one to fall out when we get the ring back. They promised 2 weeks max then we should get our ring back. Yet again after numerous calls they kept making excuses and promising new dates. On the 31st we went to the store to want to speak to the manager, just to find out the store is temporarily closed and no one knows when it will be open again. I phoned the Baywest branch and they arranged that the jeweler deliver my ring to them. Baywest phoned us the 8th of Feb to say the ring has arrived. The morning of the 9th of Feb they phoned us to urgently come collect our ring as they are also closing until further notice. We picked up my ring that same day (Friday). Sunday the 11th of Feb, the stone right next to the repaired stone also fell out!!! 2 days since I got my ring back. It is still under guarantee, but now I have no store to take the ring back to for repairs!!! It is going to cost me money to take it to a different jeweler for repairs due to NWJ terrible quality and service, which I think is completely unexpectable!!!!! We tried reaching NWJ Head Office but also with no success. They do not answer their phones nor respond to any emails
