Bullying a child

I'm at a loss but I'd be more upset about this but I was happy with how it was handled

Our children all play sports in a league for special need children. Yesterday was the volleyball playoffs.

My daughter is in the 10-12 group
Joel's boy 8-10
My son 5-8

my daughter is a good player but a amazing server. Most teams struggle to return her serve.

Well it seems someone was trying hard to get her disqualified
1st time the official said someone questioned her ask. She's tall for her age.
I had to prove to them she was 11
2nd time someone complained she wasn't in uniform. Most of the kids wear basketball ball shorts but my daughter only wears cotton leggings because of her sensory issues. I had to show the official the rules and that She's allowed to wear them.
3rd there was a complaint about her wearing ear buds. Again there is no rule about it.

After the 3rd complaint the officials actually went to the family and turns out their child isn't even special needs. He just wasn't very good at volleyball and the father thought our group of kids would be a good place for him to get better. Well the family was kicked out of the game and banned from playing.

I am at a loose that someone would have their children pretend to be special needs just to get better.

Anyway
My daughters team got gold metals
And the boys got silver.

Now we get a few weeks off before basketball starts up
