Not that it helps, but I think this is only a problem if you’re paying by credit card.
If your company is on an enterprise plan, at least for us all of the limits are pre-negotiated and prepaid, and you aren’t billed for overages (although if you consistently overage, sales will start badgering you to negotiate a limit increase, but my experience is you can simply ignore their demands and they eventually go away)
It does drive me crazy that their enterprise tier “caps” bandwidth. Our company overaged on one of our domains, so we moved the domain out of our enterprise license onto a self-serve plan, and like magic, back to unlimited bandwidth.
