Bad communication

I contacted the school. We had problems last week. Then the matter was resolved. As something else came up I needed to sort the matter out. I spoke to Ronel and finance and she dropped the phone in my ear and Tania at the school just told me she can not entertain me and put the phone down in my ear. The headmaster i am trying to reach for 2 days already. If they treat the parents like this. How are they treating the learners. This is the worst i have ever experienced from people. And this people in the office are making the school bad.
