Looooong wait

My fibre for my Internet went down last weekend for 3 days. It then got repaired. This weekend it died again. So far its 4 days this time, tomorrow is day 5. I logged a call on Saturday and when I called just now (Monday afternoon) I am told that I will get a call from metro fibre to let me know when they will repair it. So they have no idea when it will happen. So for 8 days this month so far I have had no fibre. So why am I paying the full months subscription when I have not received the service? They talk about a 72 hour turn around for repairs, but guaranteed they will want their money on the 25th of the month, whether they have delivered the service or not.
