Vumatel installation guy is rude and ***********

I app**** to have fiber installed at my house and the installation was for 10am, but the installation guys came at 13:22. The very 1st guy that came to my house was so rude and didn't even greet even though I greeted and just told me how he struggled to get hold of me. I then told him that I am the one who called from 10:30 to the guy who took my details and their office line and my phone has been receiving calls but not from him. I showed him proof, but he failed to show me his. I do not care about his attitude coz it stinks, but what I care about is the fact that before Vumatel fiber gets installed, you pay. As I paid on Friday the 15th Nov, this fiber hasn't connected at all. Even the email of activation confirmation is incomplete coz there are no details of my ISP SADV for in case I have problems or concerns. I want my money back and have this taken out coz they left before ensuring that it works. I think they did this on purpose because he even went about the time being lunch time and asked whether I don't cook.
