Hi Hammer,
Click on the ACCOUNT button that's above the PLAY NOW button on the left hand side. Once the account page loads scroll down to the button and you'll see your recent transactions. Click VIEW ALL at the top right of the transaction list to see the entire list.
If you were charged for the purchase you should see the deposit amount reflected on your transaction history and the credits should show on your account page or at the top of your friends list. If you do not see the credits or deposit on your transaction history it's likely there was an error with the purchase and it did not complete successfully.
If you see a deposit amount and no credits on your account page then please email customer service at members@worldgolftour.com so they can look into the matter for you.
