Accounts do not automatically receive a promotional code. They are offered by third party or by an advertisement to sign up for AdWords. Then, there are certain requirements that must be met, then a user can manually add them to their account, then meet the requirements and finally receive the offered credit to their account.
Where did you learn about your promotional code? Who offered it? What are the requirements? Did you add it to your account?
