Bad fibre service provider

I revieved the worst experience with getting my fibre line activated after the cancencel my line at my house. I loged a call for my wifi not working and they cancelled my line. 5days and i am still strughling to get ig working. The supervisor put the phone down in my ear when we phone nobody can help us and just telling us to phone vumatel ourselves to sort the line out . What a bad service after paying everymknth and having 2years my fibre with them but when something is tbeir fault nobody want to hrlp and you need to wait for them
