AdWords account has been suspended because my billing information
Re: AdWords account has been suspended because my billing information
To check your billing details are correct, please go to the Billing tab in your account and then the Billing Settings tab. If you see any links to 'Re-enable your form of payment', please make sure that your billing details are correct and follow this link.
If you're still having problems with this 24/48 hours after double checking and renewing your form of payment, please contact the support team directly to discuss the specifics of your account.
Hope this helps!
