Google checkout just shutdown us down

5 months ago, one of my projects signed up and began using Google Checkout to allow customers to charge service available on our website. A week ago, out of the blue, Google erroneously flags our Checkout account for violation, indicating that we are not charging items from the website we say we are. The email indicates there are 5 days to take action. I double and triple check that all the information in our account is correct. Then send emails and feedback indicating everything is correct. I hear nothing, then today, 5 days later, Google shuts down our account. After franticly trying to fix this, or call someone, search this out, I find there is no phone number to call, just a feedback form which does nothing. The account is suspended with no further action to take. My website it dead in the water. What can I do?
