About to get fired because of Vox and Vumatel

We ordered Fibre on the 27th of October. Tuesday 31st Oct installation was done. 1st Nov router was delivered and maintainance guys failed to stabilise PON. The whole week we have been calling to get the fibre to be connected but till today zero connection. I work from home and received my first written warning on the 3rd of November for not being online and working. We spoke to a consultant who said it will be connected remotely within 4 hours. It's been 3 days and nothing has been done. I don't know what excuse I'm going to give at work today for not working. My clients have been sending complains that I have not rep**** to their emails and that I'm AWOL. Why is it taking more than 10 days to get connected, do you employ people you do not know how to do the work? Can you please get someone to come today at 8am before I get fired at work.
