I am really disappointed and disheartened

I went to the Carletonville Nedbank branch around May to query about a transactions that went off my account just after I had received my retrenchment payouts as I did not know this transactions and wanted clarity. This was a large amount and have been sent from pillar to post about without clear explanation about it. Yesterday the branch manager for the Carletonville Nedbank branch called me and I attended to her call in person at branch today. She requested that I bring along my child in case I did not understand the explanation she was going to give me. When I got there, I had to sit and wait for her to attend to me (for more than an hour) . When she finally attended to me, she called me to her office and told me that she called me to give me feedback on my query. Her explanation did not make sense to me as she told me that I made the payment myself using my card and pin to some attorneys that I was handed to (of which I do not recall of). When I told her that I did not make such payments she insisted that I did and I must have forgotten. I am not satisfied with the service and treatment9.
