Worsed Internet Fibre provider Ever

Their service has really been **** this last couple months. Fibre was off almost a week early in May ,numerous calls...same thing restarted router countless times, my wife eventually sorted it out doing their work and phoned vumatel.. now again the fibre has been off since 21 May up to now...they can still not find the problem,then its my router that's faulty...then its the line that has to be checked, it has been so frustrating getting nowhere. Paying for a service that's totally absent...does not help having a handfull off ticket numbers...can not even give any idea when problem will be fixed.
