Once you request an online return, collection takes roughly between 2 and 4 business days, checking the item and starting the refund can take as long as 7 business days, after which your bank may need as many as 14 further business days. Refunds return to the payment method you used, or, if you choose, onto an e-gift card. Paid cash on delivery? An online return gets you an e-gift card, while a store return gets you either a gift card or cash, and the fee you paid for cash on delivery is kept either way.
Delivery charges come back only for a faulty or damaged item or one that differs from your order, and a partial return never gets them refunded. Direct exchanges aren't offered: take the item back to a store and make a new purchase in the size you need, which is why it pays to consult the product page's size guide first. To cancel an entire order, ring 8004414440 during working hours and within an hour of placing it; after that, returning it is the only route.
