Disgusting service

I have been trying with the help of Nedbank to change our debit order since March. Pertunia Masigo a data capturer had a query which I then answered and got no reply. So, the D/O now reversed as I do not use the old bank anymore. Today Cartrack phones me from the accounts department about my account and the lady was very rude. I do not appreciate this as we have been trying since April to change these details. Speak to your rude staff
