Bad service from Harris Jewellers Canal Walk

Very disappointed with the attitude of Mr Harris - I bought a bracelet for R9,5k 4 years ago - 3 years ago the chain that linked the gold baubles had stretched to twice its original size and I took it back and paid R400 to have the chain shortened. The clasp broke recently and he said it was not repairable - if he did repair it he would only have a 50% chance of lasting - he could put a new clasp on but they couldn't show me what clasp they could fit or how much it would cost me - the current clasp is an integral part of the bracelet and without it the bracelet is just not going to be the same. He was totally disinterested in trying to resolve the issue and disappeared to the back of his shop and left me with the sales person who tried her best. I left his shop with a broken bracelet that I will never be able to wear again
