A “manager” is not going to be able to do anything more than what is currently being done. You reported them. You gave additional information. There is nothing else you can do. Bot reports are handled in the order they are received. Your report is not more important than someone else’s bot report.
If the player you reported is using a bot program, Blizzard could be monitoring it to see what it does, how it works, what possible exploit it might be using. Can they detect the specific program? Can they break the exploit without breaking the game? Then they do a mass-ban. It is much more effective than the whack-a-mole method you are looking for in this specific instance.
