Am sorry about your GCMS note status. Unfortunately, you can do little or nothing about it than HOPE!.
Talking to the agents is useless. 99% of the time, they don't know where to look and even how to answer your inquiry. An agent actually told a friend of mine that her eligibility have been completed and everything is good. That it just remains a Senior officer to look over and send PPR. However, the case analysts' recommendation was a failure (<67 FSW) and called for a review of eligibility. She was eventually refused. Even in my case, I begged two different agents to let me know if my eligibility was recommended: passed, for additional review or met. They kept telling me that it is still in progress until I got my GCMS note. Its completely a pity!
Maybe you can just request for another GCMS (since its just $5) while waiting for this one. It will save you time and may even contain more new information.
Goodluck!
