Bad service

My Fibre has been down since the 12th December and today is the 24th December 2020 and still not connected. I have complained to SADV and each time.a new case is opened which means you have to wait for 3 days (because that is their response rate). Well, it is now 12 days and between VUMATEL and SADV the problem is not fixed. SADV just log a call with VUMATEL and there is no follow through! So frustrating! You pay for a service that you can't even use!!
