I want to disable or lower the current on-demand or pay-as-you-go(PAYG) budget.

If you already used some of your budget within the current billing cycle, you won't be able to disable it or set it to a lower amount than the value of the events you already used.

Once you enter a new billing cycle, you'll receive the charge for the on-demand events, and you'll have the opportunity to lower the amount or disable your budget.
