Horrible customer service

This company and their customer service agents need to be held accountable for not providing the correct information. I spoke to a lady by the name of Legogang she was utterly rude, and when i insisted on speaking to a supervisor I was informed he/she was extremely busy and did not have time for my petty query. On the 27th i deposited money into their account because the debit order failed later the amount was debited again i asked for a refund of my money via email. I was ignored and transferred to multiple people. When i called today this lady lebogang told me that I'm wasting my time because they would not give me my money back, no matter how many times i email or phone I am just wasting my breath, airtime, and data This was never agreed upon and the terms were never discussed with me. I later asked that they please refer me to the person who spoke to me the very first time my account was handed over to MBD who gave me the details the same lady told me there's no way she would ever do that, and I would not have any opportunity to speak to them as i will be shouting at them since I know the terms now I should be happy and just go with it. I don't have the branch name but here are the names of the people who i emailed back and forth SIBONGILE PRECIOUS MBOYI,FAITH KHANYI, Ingrid Peters FLORA MALEFO MOHALE, this is also the number which i phoned and spoke to Ms Lebogang who sounded like an elderly women +***7 ***
