Please note that payment permits approved under the GF or G7 condition must be cancelled before 23:59:59 hours of the same day of approval. If the payment cannot be cancelled, you are required to submit a refund application instead. Otherwise, cancellations for payment permits approved under the GF or G7 condition (as well as G1 condition i.e. payment by cash or cheque at any UOB branch) that are submitted within the permit validity period will require 5 working days for processing due to the time needed to verify the GIRO deduction.
