Poor Fibre Support from Cell C

I've had a fibre contract withh Cell C now for almost 2 years. At least every two months, there is an issue with connectivity, it either drops,or have no connectivity at all. Then, when trying to call the support desk, you end up holding the line for 20 minutes (who do you think pays for staying on the line?) I haven't had connection since Sunday, today (Tuesday) I called again, and the fibre team is not available (they are NEVER available) When asked for a turnaround time, none can be given. Terrible service everytime I have to deal with support. What an inconvenience for someone that works from home and are dependant on internet at home.
