Poor Customer Service Skills

I went to my Bank to query an unauthorised debit order. The consultant on NO 8 assisted me however he could not dispute the debit order. I asked him to check who are these people debiting my account, he said he'll call someone to help. He then asked me to open the app on my phone to check their details. He left me writting down the details. A lady came to the desk, greeted and spoke the consultant next to her. She said to me you are red flagged, i asked what do you mean, she explained about the loan i took in 2008 that was handed over. I said to her i assumed you came to help me with this debit order i came for. We started arguing, i told her if i was her i would have said "Good Afternoon Ma'am my name is Bonisile i'm here to explain whatever...not to just tell me about the handed over account" solve the problem. I came for then proceed with the account you wanted to explain. She told me the consultant is on training. We ended up exchanged words unneccessary, then i stoop up and left. She even refused to give me her name and surname as i have asked for them. She wrote them on the paper. I am not happy with your service Manager BOITUMELO that's all i heard from you I'M THE MANAGER
