Vumatel just closes ticket without actually checking the fault is fixed

We have now been without fibre for 6 days...every day we phone the ISP and sit on the phone for 30 minutes to test everything again and again...Now we are told that Vumatel closed the ticket and they have to log a new ticket and wait 3 to 5 business days. After day 11 will Vumatel just close that ticket again??? Making it impossible to work from home and killing small businesses here...
