Three major outages in less than a week. Very bad communication and no tangible action taken

I have been a client for just over a year and in that time the service has dropped significantly. My complaint is about the recent outages experienced on the network. Unless I'm very much mistaken there have been four major outages in the Cape Town area in the last 2 months. I rely on my internet connection for work as I do social media posting, when my internet is down I lose money. The explanation we get on social media is sorry check our announcement page or make other arrangements. Sorry but I pay for a premium service based on the best ISP in SA awards and this is unacceptable. What is the company going to do beyond a sorry for the inconvenience excuse? Will I receive a rebate on my Invoice?
