I had a similarly frustrating experience with Feedburner in early 2008. I was running something slightly controversial and they basically reverted to an older version of my RSS and wouldn't let me do anything to change it, including redirecting the traffic away from Feedburner. I emailed the Google rep I had dealt with in addition to trying all their listed means of contact with absolutely no luck. The EFF told me that their terms of service probably (and did) have a clause that they could discontinue service to me for any and no reason (which is how it seemed). Since this was for a podcast I decided on a whim to try emailing Steve Jobs too. I had full control of my account not an hour later, and I've been happily on Amazon's S3 ever since.
