Hello @Saleh Bagheri ,
It sounds like you potentially linked a work account when you intended to link a personal account. This will require migrating the credits to the proper account.
You will need to work with a billing engineer to help assist with this matter. Can you please create a ticket here with them to have them ensure your credits are assigned to the proper account?
Please don't hesitate to reach out to us if you have any other queries.
Thank you.
