Apple subscription refund takes upto 30 days?

I have requested a refund from apple for this purchased item as it was an unexpected payment on 7th June and the request has been accepted and showed me the refunded status in the status. Since this is a card payment, apple has provided instructions to wait for 30 days for me to claim the refund from the bank. Now it has been 27 days since the refunded date, but I haven’t received the amount or any notification from Apple. Im expecting that Apple would let me know the status of this as soon as possible.
