Here’s an example with PayPal:
This is an increasingly common issue now that India’s banking regulations have gotten stricter. Banks there have a tendency to decline automated payments on a regular basis. As soon as the user manually re-subscribes, the bank starts paying again, only to repeat the same issue a month or two later. What could’ve once been considered a rare edge case is now a common occurrence.
- Alice subscribed to an upgrade with monthly payments.
- For whatever reason, Alice’s bank declines the payment the following month.
- XenForo downgrades Alice when payment lapses, as it should.
- Alice notices that she no longer has an active upgrade and goes to the upgrade page to investigate.
- XenForo offers to let her purchase the upgrade again. This is a bug. Alice takes this to mean that the existing subscription has been canceled. XenForo doesn’t provide any option to view or cancel the existing subscription.
- Alice subscribes a second time.
- PayPal keeps the existing subscription active on their end and may attempt a second charge, which Alice’s bank may approve.
- Alice is never notified or given an explanation as to what happened, aside from a duplicate receipt. Unless Alice notices and contacts the forum admins, she’ll continue getting charged twice.
