Poor quality overpriced jewellery

My 5th wedding anniversary is around the corner and sadly I don’t have a wedding ring again. My husband proposed to me 5 ½ years ago. He bought my ring at #Brownthediamondstore. Since I’ve had the ring 8 diamonds have fallen out. My ring has spent more time in repairs than on my finger. Last year I demanded that they remake my ring. They agreed to remake the ring. Less than a year later another diamond fell out. Now they are saying that I have been negligent with the ring. They have checked the ring and they have found knocks on it? I don’t do boxing, don’t go to gym, don’t do dishes or shower with my ring on my finger. I work on a PC all day and I drive. How in the hell would I have managed to knock the diamond out of the ring? I’m currently wearing a R40 costume ring. I’ve been in their store banged the costume ring on their counter and guess what??? No stones dislodged? Do they think I’m dumb or something. I’ve been speaking to AMY from their Customer Care or should I say “Customer DON’T CARE” dept. She has been totally useless and very condescending. She has made it very clear to me that it was my fault that the diamonds keeps dislodging. She also pointed out that they have remade the ring for me last year. So I should be grateful that they did me this favour. As if I got the ring for free. And if I want the ring repaired I should pay R1600. She suggested that I go into their store and see if there is another ring in their range that I would like to swop my ring out with. There was nothing in the same price range. I did find another style similar to my ring which was more expensive. I asked them if they could design one for me in my price range and she flat out refused to give me that option. I demanded that they give me my money back for the ring. AMY then told me that I would only get back the money that was paid to them 5 ½ years ago? And yet the appraisal amount has almost doubled? I am very disappointed about the way this situation has been handled. I'm also questioning the quality of their jewellery? Why bother paying a ridiculous price for a ring that you can't wear? What is the point? I have lodged a complaint with the consumer protector who has made contact with Browns. Amy wasn't phased by this in the least. This is a perfect example of how the consumer is being exploited. And contradicts their values; Exceptional customer service, high grade metals, cutting edge craftsmanship...I don't think so
