Poor service : dissatisfied!

Our fiber has been off a couple of days and we have called in for assistance but we have been told that tickets have been logged for someone to have a look at what is wrong. Another agent said that it's our power that off - our power is perfectly fine. We paid for service but we are not receiving a service from Vumatel right now and we are purchasing data as we need our internet connection to run our business from home . It is also school holidays!!!! We have made 3 calls but no one can assist us. This is our last resort before moving our service else where . Thanks
