Fiber line

After having a vumatel fibre line for over two years during which time the line went dead 3 times the line has now vanished into thin air and I have been without internet for over two weeks. Vumatal has closed the ticket twice and still not told me what is going to happen. Everytime I call the center agents treat me like I am inconvencing them by wanting to know what is going on. The manager I eventually managed to get hold of informed me that I would have my internet restored on Tuesday. It is now Saturday I have no internet and no one looking into the problem.
