Once your order has been confirmed, it's not currently possible for you to change it prior to dispatch.
You have an option to cancel but you need to be quick about it. Please call Customer Service immediately, and they will do their best to fulfill your request.
However we cannot promise that they will be able to cancel the delivery if you have already received an e-mail confirmation stating that your order has already been shipped.
If your order has already been shipped, you will need to return the order to us.
