I have some ideas you can try, but while there are moderators here, this is not a general support forum. However, 24/7 Support is available at the link below.
Anyway, here are my ideas. 1.) The order did not go through. Did you get an emailed receipt? 2) A very common issue is that you created a different account when buying the domain. Check your emailed receipt to be sure you're in the correct account. 3) There is a typo in the name and it doesn't match what you are searching for. Again, check the receipt and the domain spelling.
Those are the things that come to mind immediately.
I hope that helps,
