Extremely poor and pathetic customer service!

Not even 2 months after my bad experience with Nedbank, it happened again! I have payment arrangements for my credit card which I pay timeously every month. Last night an amount of R312.90 was debited off my account for my credit card. I called the call centre and was told that they see that I have payment arrangements and don't know why my account was debited. And that if I want this transaction reversed, I need to go into the branch. The mistake was done by Nedbank so I don't see how this is now my problem and that I have to go into the branch to get it reversed. This service is completely shocking and I am really considering closing my bank account and banking at another more efficient bank. Nedbank you really need to get your act together, the customer service is disgusting! Now I have to make time to go into the branch (where I received poor service the last time) to get something reversed that Nedbank incorrectly did and "don't know why it was done". This is a complete inconvenience and I don't see how this is making banking easy for me. So disappointed with this level of service.
