Disappointed Parent

I am very disappointed at your accounts team, earlier in the year we got threats saying that the kids would have no school because of an oustanding amount that was calculated incorrectly I have since spoke to probably half of the call center with no response, I spoke to Ntebeleng and her Team Manager Lisel and she left me hanging from a "possible cancellation" I have no gotten a new one saying we owe R17 394 this was sent in September which also still doesn't make sense, a month later I recieve a new statemnet with a balance of R23k and I was told it was brough forward from a decemeber overdue balanace bu we paid that and sent all payment refences but still nothing, can we please get the correct statement with the correct balances, I have contacted the school numberous times but that was useless because your automatated email address noone checks that inbox and on top of it your call center has so much call advoidance, they hang up on each call when it is accounts or mute the call till you actually hang up. Can I get the correct statement please with what is owed and not made up amounts that have already been paid and sent with proof of refence.
