Useless Customer Care

It has been 8 days and my fiber service is still down. Have logged 2 service requests tickets, have made numerous calls and sent numerous emails and I still have no resolution. The call Centre operators say they will escalate the problem, but nothing happens. My first ticket was closed, and Vodacom attributed the problem to Vumatel. I pay Vodacom for the service not Vumatel. This is shocking service from a supposedly "reputable" company.
