Axxess terrible customer service

I have received the worst customer service from axxess, I have reported multiple times that my internet connection is slow and everytime I am asked to do a speedtest connected to the ONT and when I do and send to them they do not respond. I decided to upgrade my line from 10mbs to 50mbs hoping that the internet speed will improve the has not been any improvement which affects my productivity as I am working from home. The last draw is that now I do not have internet axxess I have been reporing this for the passed four days and the response I receive is that they have logged a fault with MetroFiber and everyday I follow up on the fault they ask me to provide FSAN number. I have provided this number everyday for the past four days with no solution. They blame MetroFiber but I have an account with axxess who debit me over a thousand rand every month not MetroFiber. Anyone reading this please recommend a good fiber internet provider in the Midrand Halfway Gardens area.
