National Bank of Malawi plc has resumed normal operations at its Customs Road Service Centre after a power-supply problem. In a notice to customers, the bank said the centre's electrical difficulties had been resolved. The outage prevented the branch from operating normally for a period. To compensate for the lost time, the centre will remain open for one extra hour. The notice gave no reason for the failure or estimate of its duration. Customers can once again use the branch for regular transactions, with the added hour intended to reduce the disruption.
