Since SlicePay doesn’t know when a customer cancels their order with the merchant, we wait for the cancellation confirmation from merchants. Usually, merchants send confirmation within 7 days, but it varies for different merchants. SlicePay will refund the cancelled transaction within 2 working days after receiving the confirmation.
Bill gets generated on 1st of every month. It might be possible that cancellation confirmation is received after the bill is generated for that period. In that case, too, don’t worry. Your cancelled transaction will be visible in next month’s bill.
