Bad service

Mweb service is atrocious! We placed the Fibre order 4 weeks ago, they have messed up the connection since 2 weeks of putting up the line, still not connected despite sending numerous emails and making numerous calls with no resolution as yet! No one from mweb has called to rectify this issue and but rather they passing the blame onto Vumatel.Vumatel has been assisting and came to check the connection twice and advised it is an error on mwebs side. How much longer must a customer wait for this to be resolved??
