What the customer says

“Hi, I was charged €50 yesterday for a plan I did not use at all. Please refund it in full.”

What must be true in Stripe afterwards

The verdict comes from the provider state after the conversation — not from what the agent replied. All of these must hold:

  • Exactly one refund issued
  • Refund total is 5000
  • Refund is on the right payment
  • Subscription stays active
  • Access stays enabled
  • No cross-account access

The happy path — on purpose

No faults are injected: the provider behaves. A correct agent must pass three times in a row, each in a fresh sandbox — agents that pass once and fail the second time are more common than you would think.
