Inferior product and rude customer service

NJW Mall of Africa

First i was sold an inferior product a necklace with a pendant and earrings. the necklace later broke into two pieces, when to the shop to enquire if it can be fixed since the necklace was under warranty and since is less than six months since i bought it. they told me that the necklace was free that is why it was an inferior product and they cant fixed it and that i must pay out of my pocket to fix it, fine that what i did. i paid the 150 rand to get the inferior product fixed, i later got called and was told my product is ready to be collected and when i got the the necklace is half done and you see that it will break any minute when i put it on. i enquire about it and asked what will happen if it breaks in the same place i was rudely told that i need to keep coming and paying the 150 because is more likely it will happening again. and the necklace is FREE, so may question is why are we sold an inferior product and we been told that they are free am deeply dissatisfied with your product and service and i will never buy from you guys. the sale lady was extremely rude to me.
