I also got a phone call from the staff today,
she told me there's already a p.m. vacancy for my girl,
but she asked me to attend an interview next week.
I suppose she means my girl is being accpeted, but after i read your post...
then i better train my girl for better performance la...
I think you just need to look at things from different perspectives. I don't think the school is wrong (the worst is probably the staff told you on the phone your child had been admitted), you neither. You both hold different perspectives on things.
$500 is just a small sum, don't be angry.
