Getting Past Procurement

Anyone have any good strategies to get more information out of procurement? I'm in Federal and when it goes into the machine, it can be a big challenge to get any updates from my champions or the end users. Good news is it's in procurement. Bad news is the normal response is "it's with procurement." On occasion, I've been able to get a procurement contact from the end users but it seems they've almost always been coached to hate/ignore sales reps reaching out. On other occasions, they are entirely unwilling to even provide a contact. Your boy is just looking for an update and to make sure they're tracking! Hook a brother up! Any ideas or things you've found useful would be helpful.
