Bad service from vodacom

Very disappointed with their service in the area of Fiber. I have been cling these guys for past 2 weeks now. They handed me with a reference number but every time i call them they hive me a new story such as "we are in process of swapping out your router" or " we will repair it oline". No one comes or repairs the router but they charge us with a heavy bill every month. This is so frustrating because out work has come to a halt and Vidacom has no rehard for crm services.
