EDGARS Gateway luxebox poor service

I had sent my son to gateway to buy a watch for a friend from Edgar's and he bought it from a company which is renting in Edgars called Luxebox. He had come back and showed me the watch, however the watch which was a Signature watch was faulty. He took it back to the store and was informed by the manager that there was nothing wrong with the watch and he can't do anything about it.. a few minutes later as the salesperson had the watch in her had the watch stopped working and he then told my son that he would refund the amount for the watch but he doesn't have money. He said come back in 2 days but two days later he said that he still didn't have money and that he can't take out from the float to return the money. This manager of Luxebox named Seelan didn't have the decency to contact us to notify us of the situation on the day he said come to get the refund. It's a poor reflection on a company like Edgar's that this is happening in their own store at gateway. It's the first time I heard that a company that can pay for their space to another company can't refund R800. It's a disgrace. Luxebox should take note and so should Edgar's gateway.
