VOX - BAD| service - Line Upgrade - 3 weeks still in Progress - Not complete

I app**** to upgrade my Fibre Line from 10/10 to 100/50 on the 19th Aug 2020, by the 31st Aug nothing was done, I got a call from Vox saying that my order for upgrade was not yet sent to Vodacom on the 1st Sep 2020 called Vox again to find out whats the update, they say error made when I requested upgrade was sent through as a New Installation, 1 week later sitll nothing happened, called them continuously with no call back from anyone, Contace the Area manager, sent email to concerned but still no joy. Vodacom called on 7th of Sep saying they making an appointment to install fibre to the home, I told them its not a new Installation only and upgrade 2 hours later they called and confirmed line upgraded to 100/50. On Tuesday 8th called VOX once more and everyday since then still not yet upgraded. BAD service from them. Called again this morning 14 Sep 2020 told that error on line they logged to Vodacom @08:45 they fixed, but my fibre to home still not sorted. What is most surprising VOX sles pitch in 2 days we can get it upgrade or 3 days, its now 3 weeks later still nothing.
