I have been approved for a refund on 89€ for online subscription. It may take 30 days according to terms. But very soon I have to reopen a new account in the same bank (credentials will be changed). Will my refund come to a new account, if I will add a new payment method to apple?
You’ll need to contact the merchant, Apple, and see if the refund can be sent to a new account. You should also contact the bank that issued the card you used as the payment method. Bank >may< be able to redirect the funds to the new account.
Was the online subscription an Apple subscription?
It was done in App Store for iphone application, so I guess yes.
refund on another card/bank account
