Cell C home Fibre not working

I have a Fibre home contract with Cell C. My network has been down for the past three weeks now. I have be calling their Fibre support time without any help. I have asked them to send the technician to come and have a look at what the problem has been, as the office staff can not help. Up to now they have not been able to help me, but they will be debiting me the full amount at the end of the day without having provided the service that they are suppose to provided. I am soo disappointed with their Fibre support team.
