I made a telephone appointment with this school for today 06/16/2020 at 10:30 am, at 11:00 am I received a call, until everything is fine .... But there lady who called me was very rude, she barely answered me very coldly, limit she wanted me to know the answers to my questions .

How to follow up on an application in such an atmosphere?
