Bad Service from Call Centre Staff

At about 13h00 on 21/02/2018, I called the Call Centre on ********** . All I wanted was just a simple question in connection with a returned debit order. I have been transferred to 4 different people. The 4th lady, named Botswana, gave me such an attitude when I told her I hoped she would be able to assist me as she is the 4th person I was talking to. She blatanly asked me and what if she cannot help me. I told her then she should call her superior to come and help me. I explained my situation to her, and she said she cannot help me or asked for a client. I insisted I needed to speak to superior. She placed me on hold- for 20 minutes. Now you call that customer service!! FNB staff is not trained and very rude.
