Fibre line off

I find it funny, our fibre been off 2 full days maybe and a bit. However payment needs to be made on time. If we do not pay on time im sure the line will get cut immediately. So what happens now that its been almost 3 days now in total. Midnight tonight will be 3 days. What gets done then? Cause if i as a customer should be late i will be held accountable for extra fees or line being cut. Another thing is that the agent said yesterday and today that they dont get told when it is resolved . We would see randomly it works.
