Incompetencent service

I took my lunch time to go to the bank to get help with two unauthorized debit orders upon my arrival I was asked what I am here for in front of 6 people who were standing around the front desk. I found that disrespectful as people who came to the bank their requirements should be confidential not all people knowing what a customer came to do. After that I headed to one of the staff members who had to assist me her name as Bongiwe she had abit of attitude not friendly to speak to and she could onlt help me with one reversal even after I explained to her that I once revsed that debit order she could not help! I then further told her that I need to cancel the rewards as it not helpful and don't understand it she told me they are short staffed and I need to make a call. I told her I do not have enough time for that as it's my lunch but still failed to assist. This bank is *********** and reduculas like the staff memeber who do not know how to be competent.
