I have an email and a fax number but not a direct number to call. You could always call MS and ask them to transfer you to member admin. Getting through the cue to member admin directly is essentailly impossible, you have to leave a message and ask them to call back. Personally I'd give them a week or so and then send them a letter that says since they haven't responded, you are closing. It's true there might be a catch 22 as you really need the Waiver to record. That's a question for the closing company.
