Utter dissatisfaction by Vuma/Flycool

They are the worst ISP, our internet has been down for almost 48 hours in our area. There has been no form of communication from customer support (or anyone else) regarding what the issue is or eta on the restoration of our internet. I sent 2 WhatsApp messages and an email two days ago, to date there has been no response whatsoever from them. Come next week Wednesday they will bill me the full amount like they never inconvenienced me. I mean any form of communication would be nice, some of us work from home and depend on the internet to do said work.
