My brother's phone was taken off of him because he used not even in the class, when I'm tried to make a deal with the school about to give the phone back ones of the teacher who I'm talked said she gonna make it sure he get back the phone but he didn't, so we couldn't reach him I'm called again the school about where is my brother and who is responsible for him and for the phone if anything wrong happen, and the house head teacher simply hang up the phone on me while we were talking. Seriously these kind of teachers trying to teach our kids like liars and who can't even reach a professional level to dealing with parents? So disappointed
