With an online return, collection needs between 2 and 4 business days, then checking the items and issuing the refund takes as long as 7 business days, and your bank may add up to 14 business days on top. Refunds go to the original card or are issued in the form of an electronic gift card.
For orders paid on delivery, returning online gets you an electronic gift card, while returning in a store gets you a gift card or cash. The fee charged for paying on delivery is not refunded.
Delivery fees are only refunded for items that are damaged, faulty or different from your order. Exchanges aren't direct: bring the item back to a branch, then purchase the other size separately. To cancel an entire order, phone 8004414440 (customer service) no later than one hour after ordering; past that point, a return is your only option.
