Fibre Optic by Telkom is Questionable

4 Subcontractors arrived with wrong equipment and failed to complete setup, told me to call 10210, call center person no 4 unable to complete setup , 7 days later after many calls Special FO tech arrives and completes setup. After having FO one day speeds vary from 1.5ms UL to 2.3ms DL to 1.5/11.2 we ordered 20mb speed. WiFi Router supp**** hangs after several hours and has to be rebooted. At the end of today 1800 the internet was gone. Our iPhones get 2.7ms UL and 9.6ms DL from Vodacom 4G . Plus no proper FO instructions with equipment so you cannot try and self fix but call 10210 who do not have FO training. Telkom can we have a proper FO Tech to attend thank you. If you cannot get the speed up to 18/19ms for basic FO there must be something seriously wrong somewhere.
