I have bought v-bucks and the transaction went in but I didn't get anything

Hello Jaiden, this is Manuela. I'm an Independent Advisor and community user like you willing to assist with this

I just want to confirm, the purchase was made using your PS5 or are you playing and the purchase was made on Xbox Console?

which store did you buy them from, xbox console store or pc, if pc then you need to sign in on a console to have them added to your epic account but they will only be usable on the console version.

If you bought Fortnite V-Bucks from the Microsoft Store but can’t find them, check your purchase history. If you see them listed, contact Epic Support.

I just bought V Bucks for Fort Nite and the purchase went through and the funds were taken off my gift card but I didnt get my V Bucks!!!

With the account that bought the Vbucks credits, go to
https://account.microsoft.com/billing/orders and check if the original purchase for V-Bucks went through, or if there are issues with the purchase of the V-Bucks credit.

If the V-Bucks were refunded on Microsoft's end, then you will have to talk to Microsoft support, and point them to the order that shows issues.

If the payment for V-Bucks shows as completed on the Microsoft orders page, you will have to talk to Epic Games support, and explain them, that on Microsoft's end the order was completed successfully.

You might also have to
check the transactions on the Epic website after signing in with the account of your son if there is a problem in the purchase history.
