Misrepresentation of product package

In the month of January, I ordered a home wifi package from telkom. I was advised that the package includes, modem for wifi, wifi extender, movie box, and telkom landline and mobile calls unlimited, and that a technician will be sent through to connect everything, and show me how to streamline movies etc., installation also included. Well I received the movie box via courier service, the technician arrived, and advised me that they do not connect the movie box, and that there was no wifi extender included in the package, and that I was misinformed. I contacted Telkom, who gave me a reference number, and I was asked to lodge a complaint via email to customer care at telkom. Despite numerous emails, and calls continuously from January, the matter remains unattended too, and furthermore, I was also charged 600 rands for installation?
