**** ray ans sold at Sunglass Hut Tygervalley centre

I bought a pair of raybans at Sunglass Hut at Tygervalley branch in Cape Town. After a few months the The ray-ban logo on the right hand side disappeared and the lenses are scratched although I always handle my specs with great care. I went back to the shop where it was purchased because I question the authenticity of the sunglasses. The person in charge at the shop was rude and abrupt and said their is nothing they can do because they said its a real pair, but I beg to differ. I mailed ray-ban South Africa and still waiting on them to reply.
