When fibre is just bad!

Monthly errors of fibre service via vumatel. Without fail the services goes down for one to two day and God forbid it is on a Friday and then you are without service until Monday. An example: My internet goes down on a Wednesday. They send me a message a technician will visit my premises on the Thursday, they even give me a time. I take off work to be there. No one comes. Following morning I phone and they tell me my problem is fixed. I tell them it is still down... I even go home to check because according to their help desk I am 100% wrong. I have internet! get home and it is the same as when I left. I speak to another consultant who insists the problem must be now with my configuration as vumatel has assured them it is fixed... An hour later of wasted time as we do the normal routine stupid tests they insist you do (you know the ones, like turn your router off, plug directly into the wall mounted box etc) Finally the consultant accepts the error has not been fixed... Now I could blame vumatel but they are not the ones that have wasted my time and effort with obvious lies. To be honest I have no choice but to use vumatel as they are the owners of the fibre line outside my home. Axxess are obviously not a big enough customer of vumatel to make them hurry-up and fix an issue.
