Yeah, no, that's not how any of this works. This is the definition of inflated self importance!
Your contract doesn't have an SLA. If you are important enough, you can certainly negotiate one - and it will be far more expensive than your prosumer subscription.
And even then you will not get a 1:168 or 1:720 SLA like you are expecting - that's simply ludicrous and totally out of touch with every reality. Even if you were a lucrative enterprise customer (which you are not) they'd tell you to get lost.

Actually, you wouldn't get a refund at all unless you suffer damage or injury, which is an high bar to prove in court and a totally separate ball game.
You do see that ratio in, for example, business Internet service. You’ll get a month’s credit immediately upon asking if they can also see the brief outage. Even typically awful Comcast was good about this. However, as you note, in exchange, you’ve probably signed a two or three year agreement with them and you’d owe the balance if you canceled early.
