The bank sent the remittance refund information because the remittance did not reach the other party's account and the funds were returned. Remittance refund refers to the cancellation of remittance before payment, and refers to the return of remittance that has been remitted but has not been paid to the sender. Remittance withdrawal includes two types: the remitter's request for withdrawal and the remitter's initiative withdrawal. When the remitter requests a refund, the remitter and the payee will contact the remitter for a refund. For the payee who has not opened an account in the remittance bank, the remitter shall issue an official letter or his identity certificate, the original letter and remittance receipt, and the remittance bank shall notify the remittance bank. After verifying that the remittance has not been paid, the remitting bank can return the remittance and remit the money back to the remitting bank.
