Which project is better?

Hello everyone! Recently, it became necessary to contact the User Support Center of one of the projects known on the Russian Internet. Because This was my first visit to such centers, then I was pleasantly surprised by the service.
And I wondered if it was like that everywhere?
Maybe someone else has had a support experience and is eager to share it.
So I posed this question. Because It is impossible to create a "graphic questionnaire", please write below where you applied, what kind of project it is and your impressions.
I also wonder how quickly they answered you and whether they were able to solve your problem.

I tried to highlight the most prominent publishers in my opinion:

Mail.Ru Group (Game Center)
Gaijin Entertainment
Valve Corporation (Steam)
Electronic Arts, Inc (Origin)
Wargaming. net
Blizzard Entertainment (Battle.net)
Ubisoft Entertainment SA
Nival (Nival Support Center)
GameNet
Softclub
CD Projekt RED
Innova
Panzar Studio

If anyone has dealt with them, please leave a review!
