Horrible service (stop the debit order or I stop banking with you)

I called Standard Bank customer service last month to stop a debit order from Gym Company on my account. The lady I spoke with said that the debit order will be stopped and I will be charged R55. I was charged R55 (I do not even understand why was I charged for this) and the debit order was not stopped. I called customer service today (14:15) asking why is the debit order still going through while I made it clear last month that I do not want Gym Company debiting my account. The lady was busy saying a lot of nothing.... I asked her full name and she said that her name is Itumeleng and she is not going to give me her surname because I am going to look for her on Facebook and she hung up. I mean what the devil? Who are these people you employing there? Do they even know what customer service is? Unbelievable!!! Standard Bank should really do something about Itumeleng.
