Vox non support

Vox support is absolutely dismal. Without internet for the last week. Everytime I phone them they claim it is the Fibre Provider and they log a call with Vumatell. Vumatel responds quickly ensuring me the line from thwir side is working 100%. Call back Vox, and each time the agent makes me reboot the system 3 times, then inform me it must be a fibre supplier issue and log a call again. No matter how many times I explain to them that Vumatel keeps claiming the problem is on Vix side and I have no relationship with the fibre provider, they just ignore my pleas and inform me there is nothing they can do to force the fibre supplier to rectify the issue. So despite being a loyal client for almost10 years, Vox have no intrest in assisting me to fix my connection.
