A deposit has not been reflected in my account.

For customers using SBI Sumishin Net Bank, deposits are generally accommodated even on weekends. Please be aware that confirmation will take time if you have not yet confirmed your bank account information, if the recipient name differs from your registered name, or if the five-digit Customer Number has not been appended in front of the recipient name. Deposits are generally accommodated every day with Quick Deposit.

A JPY withdrawal has not been remitted to my bank account.
