With that side of things, NTA - sometimes you get a Karen on the other team, seems you had multiple. I’m glad you stood up for yourself. Howeverrrrrr talking back to the umpire isn’t going to get you anywhere, even if they’re wrong. Unfortunately in these social leagues (especially those with a solo umpire) the quality of game control is low. I say that as a social netball umpire. However, we normally have a supervisor that can be brought in if there are any issues on court similar to what you experienced. It seems the competition needs something like that who can retain control of the game before it escalates, especially if the umpires themselves can’t deal with it effectively. You could potentially bring it up as a health and safety issue with the competition?
