Unfortunately, because our systems are highly automated, we cannot edit an address once your order has been placed. We can try to intercept the parcel once we are made aware of the problem. If this is not possible, It then depends on the courier and if they can work out the correct address from the details you have provided. If the courier is unable to deliver your parcel, this will most likely be returned to sender. Once we can see via the tracking link that the parcel is being 'returned to sender', we will be able to issue a refund on the products but not the postage. Please note - Tech21 cannot be held liable for any incorrect information entered upon placing an order.
