No internet for 4 days, no assistance from service provider

I found myself with no WiFi connection since Wednesday . My account up to date by the way. It is 4 days later, my ticket has not been resolved between SuperSonic/MTN and Vumatel. I am still without connection. There are no managers available to speak to. The poor call centre people are sending msgs but are not getting responses and I the customer is not assisted. This is insane.
