Terrible Service

So I app**** for a line, and all I needed was a new ONT (Vuma) and a router (Vox).3 days later Vox came but could not do anything. I didn't know that the tenants had to leave the ONT, so Vox could not install the router. Vuma emailed me on the 17th June 10h35 to make an appointment for the 17th June at 11h00, I tried accepting the appointment, which was last minute, but your systems bombed out. At 11h00 I got another mail from Vuma congratulating me on the installation, which never happened, asking me to rate the service of the installation. I called Vuma and they said the installation is complete, convincing me it was done, in heaven's name, how can it be done when no one came.I have called 3 times after that, and my request fell on deaf ears. No One could assist me. and still can't it seems. Long and short of the story is that I am still waiting for this installation to happen. WHEN WILL IT EVER HAPPEN?
