Credit Card Security code wrong?? Unable to sign in without it...

I had to create this new account in order to ask how I can log in to my real account (email mail@gmail.com). When I log in it immediately prompts me to update my credit card asking for the security code. Entering this it says it's wrong. There is no option to skip this step and proceed to my account. How can this be fixed?
