Ridiculous service delivery

So I woke up yesterday to no internet access. I called vox as they are the ISP. The ticket was logged but I'm told to wait 72 hours for them to send out technicians to attend to this problem. I work from home so I have to buy data to continue to work that is costing me in the meantime whilst they'll expect me to pay a full month's premium not taking into consideration how it's costing me whilst they have a 72 hour turnaround time. This is ridiculous honestly and this is what they call "service delivery"
