Terrible service

My cousin and I app**** for a DStv installation on 03/01/2020 the service we got was appauling they only installed the dish on the 06/01/2020 that's 1st thing then when they finally arrived the people who came to install were rude and unbecoming to me as a customer to top things off the installer filled in the form then had the nerve to fill in the comments section for me and said that I would recommend their company for service. When I asked him why he did that he couldn't answer he then took the form and asked me to sign. I signed scratched his comment and stated how I felt, he then took the form with my signature and to threw it away telling me that I need to comment on his phone and not the form. So if multichoice sees a form that doesnt have a signature or the form is has a shady looking siganture know that it is not mine. I am so dissatisfied with the service I got I don't know whether. It's because I'm black or a woman but the service was not something I would expect a company like multichoice to provide.
