Unexpected bad experience

My daughter went there for about 3 year abd loved her teachers who have left the school. We generally had a good experience except maybe the food not being very healthy, but then when i left i had a financial experience that shocked me. I realized i had left on my automatic payments for the whole year following my daughters departure from the school and that i had paid double for many months in the past. The principal of my daughter’s school never once contacted me regarding this and never contacted me despite my many emails. The accounts / finance manager of the school sent me a calculation i believe was half to one third lower that what i believed i shpuld get back but i was not able to make an accurate calculation on my own. I was reimbursed an amount they insisted was correct and i let it go. What was most disturbing was that they never informed me (as it i impossible they dod not notice). The principal of the whole school gave me an explanation but the feeling i had for that school after this incident left me extremely disappointed. Due to this experience i would not recommend this school.
