It’s important to us to treat our players’ data with care and integrity, so we do not share any more information about an account than what is absolutely necessary. A consequence of this is that we do not share the details or amounts of past payments on request. However, you can easily access your Order History with Google or Apple and see any orders you've placed there.

For Google, this link will take you to your account's order history (you may have to log in first) 

For Apple, accessing your order history varies a little depending on your device, but you can find the full instructions on this page.
