Fibre not working for over 3 days

I've been calling from the 10th of December regarding my Fibre being down and all I'm being told is a ticket is being logged and they'll revert to me but that never happens. I work from home and this is a major inconvenience, not that I need to justify this. I don't need to be told to troubleshoot anymore but for a technician to be urgently sent out at the same speed you would cut my services if I didn't pay for my services!
