I bought eldest daughter new school shoes last week but her form tutor upon noticing them Friday marched her off to Head of Year and between them they have decided they are not shoes but trainers. She argued back that they were from the school shoe section of shop but form tutor replied of course that's what they will tell you in the shop to get your sale!
They were from the school shoe section 
and I've since called up the company making the shoe customer services to ask what they call them. Have code on box and name and they confirmed they are a new range of leather school shoes which I now have from them in writing.
School are adamant they are not shoes but are now calling them pumps not trainers and she was sent out of form again for wearing them and I have spoken to the next person higher than head of year. She insists they break school uniform guidelines as she thinks they are pumps so I've asked her to provide her evidence to claim this and what part of "plain black shoes, must be flat, no glitter or studs" they don't conform too.
Was promised the situation would be resolved by this morning but of course have not heard anything - how do I get a response or how long should I leave it before I take it further to find out why they feel they aren't shoes although I have it in writing they are leather shoes and complain about the teachers attitudes
