Refusal to repair or assist! Sent back broken bangles

My husband bought me two gold bangles for Christmas from Game Amanzimtoti. A few months later, I noticed that the bangles had begun to crack and took it back to the store. When purchasing the bangles, my husband was advised that Game's jewelry carry a 12month guarantee. After a week later, i received a call to fetch my bangles as the repair was complete. when i arrived at the store, i was told that the supplier sent it back as they do not repair bangles. I have been waiting for the customer care and manager to call me back from the store as i do not believe that i can be given a guarantee for something that does not have a substance! How can you give someone a warrenty/guarantee and then tell the customer that they do not repair these kind of items! I, then, called the customer service and they advised that Game Amazimtoti and the manager must help me and they cannot simply send me back broken bangles. My husband paid R 5000 for bangles that are of a terrible quality and i think its totally wrong for Game to do this to their customers.
