No proper Fibre line support

I recently got a fibre line installed but it hasn't been working for a month. I have called the call center a number of times(and these are not free calls) only to be the queue for over 12 minutes at a time and then each call center agent advise me to do the same thing which doesn't resolve the issue. I finally get to a point of wanting to chat to a manager or supervisor and the call center agent said he would call me back but I received no call.

This is very disappointing as one of the main reasons I chose Afrihost is because of the great customer service.

I need something to be done, I sometimes work from home and need internet to do so.
