Charging my Debit Card Twice - Being Condescending

I visited the Plattekloof Branch and the transaction was put through twice on my account. After the first time I told Brilliant that it was already deducted and she was very condescending, telling me that it did not go through and that she needed to put it through again. She refused to give me back my card before she charged me again, indicating that the first transaction will be reversed. Also indicating that she will make sure it is, and if it is not reversed that I must phone. I have since phoned the branch twice, spoken to the manager on duty and both times they have indicated that they will phone me back. I have yet to receive a call back from the branch. This is completely unacceptable. First acting very superior towards your customer, like they have no idea how things work and then not solving the matter when you were at fault and not phoning your customer back with a response. This is not the first time that this branch's service has been questionable and I will certainly never visit them again...however I would please like my money back. Did the branch not pick-up that they were over for the day? Managers I spoke to: Tshepo and the second name I can't remember.
