Shocking service and double billing

Webafrica is by far the worst service provider I have ever dealt with. If you have a problem it’s impossible to resolve. There contact numbers they give you and advertise don’t exist, even there complaint email bounces back. During a simple residential move they have cut the line early, cannot activate it again and are now billing me for both the old line and new line. They have acknowledge a few times that they made a mistake but they do nothing about it. I have to try resort to blocking the debit order now, absolutely disgusted with them
