Why haven’t you taken payment?
If you’ve paid by a credit/debit card, payment won’t be taken until your order has dispatched. If you've paid by PayPal, you'll be charged as soon as your order has completed. You’ll receive a shipping confirmation email as soon as your order is on its way to you.
Your order might have been sent in separate parcels, so you’ll only have been charged for items that have left the warehouse.
