Getting a Refund After Paying Credit Bill

Hello po, may charge ako sa BPI CC ko na irrefund within 5-7 days. However my statement date is on the 9th, kaya di ako sigurado kung marrefund ito before the statement date.

What happens when I pay the bill in full, and then receive a refund after? Will I get a refund to my bank account or considered as advanced payment na siya sa next bill? Thank you!
