Clueless staff at Wesbank

All I need to do is to update my banking details so I can keep paying them but they make this task impossible. I have updated on the website, I get no answer on email and know one knows at the call center, I have been told 5 different things. Every single debit order that I have was changed with one phone call or one email but no Wesbank can't do this, it an impossible task for them.
