Cell C Fibre - non existent technical support

I have fibre with Cell C. The internet has been down since Monday (it is now Friday), and nothing is being down about it. All the lights are green, including on the CPE. But even if you connect directly to the CPE there is no internet. I have made 5 calls to the Customer Disservice Centre, and everytime they promise to call me back. *****. *********** *****. The case has been "escalated" multiple times, but that seems to be a bs story. I am at my wits' end. When I phone I am told "still no feedback". How is it reasonable to charge a monthly fee but leave your customers without service for almost a week (and counting!)? The funny thing is that the only page that loads is a sales page of RSA Web. I think I'll just sign up with them and be done with it.
