ZSL promises a refund if you tell them you've changed your mind within 14 days of purchase, and you won't be entitled to a refund if you cancel after the 14-day cooling-off period. If you have a receipt or delivery note, they will refund the original debit, credit or charge card used for the purchase. Or in the case of purchases in their zoo store, they will refund the credit or debit card provided on the completed return form.
