Maybe what they mean with that is before you try to contact them disable or update your third-parties apps, plugins, hooks, etc. and see if you can reproduce the problem, sometimes might be the cache that is causing the problem. As a developer it is frustrating to find a problem being caused by a third-party library that was not updated.
I cannot say about "scolding" but this is what I would interpret it, I have no idea about what was discussed privately so I cannot say more. I didn't have this kind of problem with the support.
