Defective Jewellery

My fiance purchased a ring at American Swiss Century City in May 2015. He proposed to me on 25 May 2015. The ring cost him R 5300.00, he had paid it over 6 months before he received the ring. I wore the ring for 1 month, took it into get a quote for wedding bands and received my ring back 2 weeks later. When I received the ring back I noticed that the Rhodium plating had faded on the 9k white gold ring, so the yellow gold was coming through. I then took the ring back and they re-done the rhodium plating in July 2015. It is now 1 month later and the yellow gold is once again coming through.<br> <br> I am not impressed as this ring was quite a bit of money, even a **** ring would last longer than this one has. Also, the employees at American Swiss Century City do not have great customer service at all and I find then to be very miserable. <br> <br> I will not go back to American Swiss as I cant deal with them as I have been in there so many times.<br> <br> I am not sure which way to turn now, and my fiance and I are not happy with the ring anymore, we don't want to have to take it in every second month to have rhodium plating done. It doesn't seem right for a 9k white gold ring.<br> <br> Regards<br> Megan
