Falsely charged

I have had to many clashes with Nedbank for a variety of reasons. From bank managers telling me rudely to find a different bank after they were unable to do their jobs properly to not being able to claim rewards because of their systems not being able to perform its basic functionalities. However, this time around I was charged for the collection of an expired card as if it was ******. This is alarming because they could possibly make a large sum of money if they were to do this to every other client considering their large client group.
