I once got banned by Google and found it difficult to find a place where I could contact support to reinstate my account. I did find a phone number but spent nearly an hour getting bounced from person to person until I found someone who was just a general support woman who couldn't handle my request due to the 'wrong department'. Instead I was asked to read one of the many FAQs you can find online on Google's many sites. They might as well have said 'Google It' in the phonecall.

If so, please let me know what happened.
