JDC Jewellery - Disappointing After Sales Service. Terrible quality

******* place selling **** jewellery!!! My brother purchased a ring from this place for R18000. His fiancee wore it for a few days and the diamonds started falling off imagine this ring's state by the time it's their 1st anniversary worse their 5th. Lucky packet kind of quality and clearly overpriced..JDC claim they cannot assist him as they only carry a 6 month warranty. Interesting so must my brother buy a new ring now since you wont repair the one he has got???
