Purchased -> Trial still not solved

Hello!

We're private school and we have Team CC license for 15 devices. 2017 versions installed and we have active subscription till April 2, 2019. By the end of the October we encountered this issue and there is no solution for now. I had a chat with the Adobe manager from Teams dep and he transferred me here​ but nothing helped. I made a package to be deployed on our 15 machines but the installation failed every time. I can provide a log, a screenshot, a VIP-number of whatever..

So we paid $5000 for annual subscription and our educational process is ruined. And now I can't even start a chat with support because there is no such option at your customer care site.

We need this problem to be solved.
