Installer not professional

On the 15 December 2017 I had the DSTV Price Lock installed. I waited 3 hours for the Installer to arrive. Each time I phoned him he said he was on his way please give him 10 minutes. He was supposed to be there at 3pm and only arrived at 6pm. I was told by DSTV Price Lock that he also should have installed a new Satellite Dish and wall mount as it is included in the price. He had to return to install the Satellite Dish. On checking the installation, I noticed he did not change the wall mount which was old and rusted. He again had to return to change the rusted old wall mount but has left me with a mount that is not straight and has rusted bolts. I ask where is the professionalism that DSTV/Mulichoice is teaching these installers? Don't these individuals have pride in their work? I have complained to the Installer and to DSTV / Multichoice. I feel DSTV/ Multichoice should assist as it is their installer. They train the installers as far as I understand. Don't they teach them professionalism and pride in a job well done. The Installer's name is: PC Soft Integrators.
