UNFAIRLY TREATED BY OK

My worker by the name of Napo Sebilo Mokgatjhane bought a plasma tv at OK Furniture Germiston together with satellite dish and the person that was helping him recommended a dish installer and after three days to install the dish, After installing the dish the tv started having problems and after some hours the tv went off. And he went to Ok to tell them and they said its not their problem. Because the installer is not working for Ok but for DSTV. After 2 years nothing has happened my worker is sitting with a broken tv. The person that was helping was Kenny.
