Wesbank Back Office a Joke!!!

I attempted to update my banking details 6 times, they said I never send supporting documents, which I did, I can clearly see. Then they send me a form to fill in to update them. I complete the form and they advise my details have been updated. I check thewebsite, my new details are there. Then the Collections department start calling me, asking for payment??? I email 5 times asking them to debit my account, then the collections department advise that they have a new process and I must activate my details overthe phone, the caller then proceeds to argue with me, so I hang up the phone.
