Poor customer service. Poor quality of goods

I bought a wedding ring at Sterns waterfall mall worth R80k (S solitaires 18ct white gold with 1.00.10 ctc diamond) on the 25th March 2019. Only started to wear the ring on the 23rd September when I got married. Stopped wearing the ring mid February 2020 because it could not fit anymore as I was pregnant. Took the ring in for enlargement end September amd received it back in October 2020. About a month or month and a half later the ring broke off underneath amd i stopped wearing it. Took it in at the store where I bought it and I've been taking it for all the repairs January 2021.

I refused to pay for the damage to the ring, the amount of money I paid for the Forever ring was a lot. I thought that the quality was good enough for it to last much longer than 2 years not forgetting that i only wore it for about 6 months.

Now the store tells me that they can't do anything. That i must pay for the damage which is now the broken band and the cracked diamomd. What is the point of buying a pricey ring?

My ring has a piece underneath where it broke off that does not look like the rest of the ring. I asked the manager about it but he avoids my question. I requested that it must go for quality check, according to him it went for quality check but i still did not recieve any feedback.

This is so frustrating!!!
