Why not have a system of pre-paid service? Cut-off once the fund dries up. This will be ideal for a testing.

For many businesses, the prospect of being cut off as a result of unexpected demand would be a serious liability, so therefore this would have to be an option -- but if it is an option, the customer has to select between it or an alternative, which is exactly the problem in this case.

Free tier is even more ideal for testing than this proposal, but the only way you can make options foolproof is to have no options.
