Telkom sucks *****!!!!!!!!!!!!!!!

I don't know where to start. So it all started 15/6/2020 with a simple ADSL speed and cap upgrade. To put it in perspective everything is in place all they have to do is make changes on there system on there end and it will be good to go. It's 30/06/2020 after more than 8 call(avg. time on hold 25min) and a bunch of nonsense exquises I have to wait two more days for it to maybe come on. I don't know what to do anymore. I'm lost for words, the level of incompetence at Telkom SA is a joke. Can someone please advise what I should do.
