****med at Sandton Arthur Kaplan Jewellers

I asked the gentleman working at the Sandton branch of AKJ to replace the mechanism in my Michelle Herbellin watch. When my niece went to collect, he insisted on cash (R1500), and that they meet at Nandos rather than at the business premise where we had initially made contact. He gave her the watch back, offered an oral warranty of 6 months, and yet no receipt. Today, a week later, the watch is already running behind schedule. I cannot find anybody to report the matter to, and nobody has responded to any of the emails I have sent thus far. Is it possible to get ****med within legitimate business premises? What does this mean? There are just no telephone numbers to call...
