No internet connection.

I had installation of fiber done on the 18th Feb 2021 and payment was made on the 15th Feb 2021. My line is still not active. I chose Afrihost as an ISP and they keep blaming each other. I receive reassurance emails and messages saying the issue will be fixed in 2 hours, then im told in the next 24 hours, then im told it will be fixed ASAP. The fault is still there and its almost the 1st of March and they will expect full payment for something they didn't deliver on. Yesterday there were Vuma installers at my place and the guy promised that the issue will be fixed in a matter of hours and today im still sitting with no internet connectivity. I work from home, so i need to dish out extra cash to buy data. This is not on. I am disappointed.
