Unhappy mother

I would like to express a very disappointing feeling about this school principle I had a situation where my child didn't come on the 15/02/2021 so because my child is going to grade 5 I called the principal and he gave me attitude and didn't even ask what's the name of the child and just shouted at me on the phone I wonder how our kids are being treated if I'm the mother called to just tell them the reason why he didn't come on Monday I'm even scared to send my child now because if I get such treatment that's means my child will get worse treatment and for what I have heard this is how he treat kids and other parents. I'm so very disappointed as a mother
