Doesnt want to go school

Dear parents, my daughter 2years+ is in childcare she has been there for a year now. And im a bit worried early this year most of the time she has been crying not wanting to go to school, she dislike one of the teacher there. Then a month later she was ok but then she cry again not wanting to go to school. She has been telling me she doesnt want to go to school. Nearly a year and she is not happy at all my 1st daughter is doing ok altho same classroom but different level. I have residents there telling me how playgroup teachers would punish children who cry or doesnt want to listen and make them stand in one corner and some residents even tell me that during outdoor the teachers there will make children stand in one corner and not letting them play. My concern is if i go to the teacher and afraid that they will mistrear my kid. Kids are supposed to feel happy to go to school, but my daughters really really hates it she will cry her lungs out. I have already reached out to the principle and the teachers multiple times. And by doing it again i am so afraid that they might thing im a annoying mother. What should i do? 😭
