Exception rails
| Rail | Trigger | Where the money ends up | Next action |
|---|---|---|---|
| Refuse: mandate not registered | Bank Alfa checks the collection but finds no matching mandate registered for this debtor and creditor. | Never left the debtor's account — no debit was booked at Bank Alfa. · The collection was refused at or before settlement, so no net movement stands between the banks. | Bank Alfa — Asha Traders arranges for the debtor to register the signed mandate with Bank Alfa before resubmitting. |
| No refund: authorised B2B collection | After being debited for an authorised collection, the business debtor asks its bank for a refund. | Debited from the business debtor and credited to Asha Traders — the money stays where it settled. · Settlement stands. The B2B scheme provides no refund reversal for an authorised collection. | Debtor — The debtor pursues a direct commercial dispute with Asha Traders, since no scheme refund applies. |
