Pathetic service from Busisiwe

I called to get clarity regarding an email that was sent to me about the interest rate. I spoke to Busisiwe who was very impatient with me and she gave me incorrect information, she told me that the email that I received was sent in error and I must ignore it. She was not willing to assist at all,she ended up saying she cant repeat herself anymore cause I kept on asking about my installment and the answers that she was giving me were not clear. I ended up asking her to transfer me back to the line so that I can speak to someone that is willing to assist. I spoke to Lesego and she was very helpful and gave me all the information that I wanted without getting irritated and what made me even angrier is that Lesego confirm that the the email was not sent in error and the amount reflecting on that email is correct.
