Unprofessional Principal

I went for registration for Grade R @8h00 in the morning, the principal Mrs Nxumalo came nd counted people in the que told to wait cause she will be taking 40 more people. After that she came out and told she closing now she can't take us anymore she is full from 65 people now she is saying she has reached 120 students from where. This is so unprofessional I even asked @work to be for what.
