Accelerit does not care about it's customers

We have been waiting for so many weeks for these people to come and install our fiber. They requested that we pay an amount of R49 and we did that 3 weeks ago but we are still not connected. There's no communication from their side, we keep sending emails to no response. They refused to refund us and threatened that should they refund us we will not be able to get service from Zoom Fibre ever again.
