CDkeys where is my code?

I have ordered and received an email, but neither the link nor the code for my Xbox credit is in the email itself. What can I do now, should I wait or what should I do? Should happen under a minute

Well, if no money was withdrawn from your account, it probably didn't work. However, I would wait 1-3 days because something like this can take a while, even if it means that it is available immediately.
