USELESS FIBER!!!!

I’m writing this on behalf of my mom who is a pensioner. She recently got fibre installed and it has given her endless network issues. We contacted Axxess to let them know of the issue but we were told to send an email which we did and since then no one has bothered to contact us about this issue so my mom is basically paying for nothing. The network is constantly buffering or not working at all. They installed the modem in my brothers room yet it doesn’t even reach the rest of the house. We would like them to send one of their technicians to come remove their useless fibre and give us a full refund. This thing was installed on the 30th of May and is already giving us problems. I made the call on the 3rd of June and no one from Axxess or Vuma has bothered to contact my mom.
