Beyond Frustrated

I had the the installers of Hypa/Vuma come on the 21st of October to install Fibre for me. I was told the readings on the poles were low and they were going to get a technician to come out to assist. Nothing happened on the day, on the 24th when I called them they had only logged then and I was told it would take 12-72hrs for my query to be attended to. Today is the 27th and no one has bothered to reach out to me even after my emails and numerous phone calls. Whenever I speak to agents from Hypa I get told they have escalated the query to the Vumatel maintenance team and are awaiting feedback. Since been more than their turn around time and all I have to do it's just wait. I am beyond frustrated, when I ask the agents to cancel the service and for them to come take their router, I get told I can't do that as the Fibre has not been activated yet and I can't cancel something I haven't used but have been debited for.
