Noone is able to confirm my area value

My account landed in arrears because Nedbank failed to change my banking details. They have taken no responsibility what so ever since my complaint. They have some ask once Policy, I have asked several times and have had no reply. I AM WILLING TO PAY UP THE ARREARS, CAN YOU PLEASE GIVE ME MY DAMN ARREARS VALUE! Your attorney group that you handed my account over to is so useless! I have called them 6 times to confirm the value and no-one can help me. You complain that I haven't paid, but when I want to you wont allow me to??? I want the arrears value please, I will also cancel the debit order with the attorney group and will start paying you directly. Latonia, your staff, today tried to reach someone to assist and she too was unsuccessful. All this on a recorded line. You are shocking and affecting my credit rating
