I would like to return my iphone, would i need the same payment card to get a refund?

It will be credited back to the same card.

If you paid by credit or debit card, refunds will be sent to the card-issuing bank within five business days of receipt of the returned item or cancelation request.

You should contact the store and ask them. My experience, generally, in retail has been that retailers can refund to a credit card without the physical card but will need the debit card. But that may also vary by retailer.

Hi

Yes you will need the same card for refund.

You have 14 days to return.
