Hello @hosny_50gege
Thank you for landing in TeamViewer Community for assistance.
You may check out your current invoice for the value from your inbox which TeamViewer has sent out when you placed the order.
On the other hands, Customer Portal and TeamViewer Support Team will be the best two options of helping you at the moment.
You may simply login with your account credential on Customer Portal to check invoices.
If you have issue on logging in to Customer Portal, feel free to give the support team a buzz☎, and they are able to help you directly.
Best,
Ying_Q
