So called 10mbps Fibre Installation results in WORST WIFI EVER!

So called 10mbps Fibre Installation results in WORST WIFI EVER!, Support and Service totally ZERO. Struggling since 2018/03/18 to get the installation properly fixed, to get support, to remove ADSL, to have a working telephone line in the house, to get the "TV BOX" from Telkom apparently included in our selected package and was not delivered constantly out of stock, to get the TELKOM APP to recognize us so that I can use the app, but they do recognize you when they want their payment, then TELKOM have all your info. WIFI is up to - buffering all the time - can't even browse on Google properly. Switch between connections ADSL and FIBRE to try and get some WIFI reception. After a million attempts in 2017 - Telkom line is still a Business line - I just give up! HAVE an open call with TELKOM ********** after this call was just closed ********** 5 - still nothing happens. Sending emails - still no support. How the hell can we get any support or service from Telkom this year still?
