How to find orders missing from order history?
The easiest way to do this is to use the order linking tool on the website. When you log in and go to 'my orders', scroll all the way to the bottom of the orders you should see a button that says "Are some of your orders missing? Find Orders". Once you click on that it will ask for the email address used on the order in question. Enter the email used on that missing order and then hit submit. You will be sent an email with a verification link that you must click on. Once you do the order should become linked to your account.
