My app uses a per-use subscription plan.
I had a situation last night where a customer needed urgent help getting my app to function properly.
The issue was they hit the capped amount limit on their App Subscription and it wasn't able to charge them for more checks.
I had to think quickly so I canceled their original subscription for them and had them update their plan with a higher cap.
I'm a little worried that I've basically lost the money from the merchant. How can I confirm that cancelling the plan didn't result in losing the funds I charged over the month?
