In Saudi Arabia, returns cost nothing within 7 days after delivery, on condition that the item is unopened, still in its original state, and accompanied by the original invoice. Products wrapped or personalised for you and purchase cards are non-returnable, and a bundle offer has to be returned in full.
Requests can be made by calling the unified number or through the support centre. For a faster refund, skip that and bring the item to a branch anywhere in Saudi Arabia. The money returns to the payment method you used after anywhere between 1 and 15 working days, with the bank determining the exact time.
