If you want assistance from the Community Forum then you'll need to explain/describe your issue more clearly and in more detail.
What exactly do you mean by "credit" here?
Monthly membership plan or cash credit or add-ons?
What exactly do you mean by "activate it automatically"?
What exactly are you trying to do what isn't working as expected?
Any error messages?
