I read through your response and it is pretty generic in that it hopes you have a common issue with the latest patch and can find something useful in the links. They do this when ticket volume are insanely high. Not ideal, not at all.
Keep in mind, GMs are not the place to submit bug reports or game complaints.
This article might help with what GMs can do.

If you don’t have a bug, and it is something GMs can do, please re-open your ticket! That puts it up in the queue.
Also you can always post on the CS forum if you want more guidance on how navigate support channels.
