Supersonic useless customer service

I have requested my Fibre speed to be upgraded from 1 March 2021. I received a notification saying my line was upgraded but it was not. I paid for the line upgrade but did not receive it even though the SMS stated it was upgraded. Since the 5th of March 2021 I have been calling, pleading BEGGING for my line to be upgraded and to be refunded for the days my line was not upgraded. Everytime I call I need to provide speed tests of ALL nature and yet NO ONE seems to know how to do their job. I have till this day 23 March 2021 not received ANY feedback!!! Connectify blames SuperSonic who blames Evotel and somewhere in between MTN! It is annoying irritating and damn frustrating to say the least!!!
