Very bad service provider

I am a client of Web Africa since December 2019, and at the end of July 2020 I received an email that says my serves will be cancelled on the 1st of August. I phoned in and waited an hour and a half on the phone before I received any assistance. its very bad service from Web Africa. I have to pay for delivery for a new sim card which I already paid for before which they cancelled and now have to re order a new sim card and I have to pay for that delivery, they didn't even phone me to ask why is there a cancellation and ask me if this is correct or anything to correspond to me according this situation. I have to work from home and need internet access but now i have to use all my data and buy new data just so that I can work, I have to wait 3-5 working days before I get response from them. I phoned them last night and its 13h30 and I haven't heard anything from them as of yet. I am currently on the phone with them and asked can I speak to a manager or anyone higher than the manager and this sales person told me his manager is currently on the phone and he only have one manager. a company that is that big don't just have one manager the have a few and the managers also have managers its now 30 minutes that i am on the phone and still no answer. Web Africa is one of the worst internet providers and wont even bother to put someone who need internet in this direction again. I cant believe that they have this long waiting time, not even SARS that is busy at month end and with this Income Return deadlines is taking that long to answer the phone when you contact them. very very bad assistance and customer care.
