Fibrestream

Called fibrestream 10 times this morning want to know the timeline when my internet will be active again. Technical department did not answer any of the calls and cannot give me any cell number or direct numbers. Will only give the managers name Jano and not allowed to give surname. So how do I resolve my internet problem. I work from home and my son is home schooling certain days of the week. It's been two weeks since the internet is not working. Technician was on site last week and said the problem is at the high tower. When I called the call center after the technician as been at my premises last week they say it's my dish which is faulty. But I received my invoice this morning for services rendered.
