Exception rails

|---|---|---|---|
| Transfer declined or expired | After the notification, Arjun does not accept the transfer — he declines it, or the request simply expires before he acts on it. | Returned to Riya — the money stayed on Bank Alfa's books throughout. · No interbank settlement was needed, since the transfer was never accepted. | Arjun — Riya can send again, or Arjun can ask her to resend to a different alias. |
