I can appreciate your frustration. This is a really annoying situation for many customers. I am no longer the lead PM nor a Microsoft employee. The program moved to India and my position was eliminated. I don't know how they're handing it currently. You could reach out to the current lead PM, Kalyani Verma. She's on LinkedIn.
Alternatively, you can email dxipsup(at)microsoft.com. That goes to the eng team and they may be able to help you. Good luck.
