Worst customer service

I would like to formally raise a complaint regarding what was, without a doubt, one of the worst customer service experiences I have received at the Eyethu Mall branch in Orange Farm. I visited the branch to complete a FICA update. When I arrived, there were only four customers ahead of me, so I expected the process to take a few minutes. Unfortunately, this was not the case. After waiting for approximately 30 minutes, a consultant from the service desk approached us and asked what assistance we required. By that time, I was next in line. I explained that I needed assistance with a FICA update, and he told me to wait for him as he would assist me. Instead of assisting me, he proceeded to help customers who were behind me in the queue. He even directed some of them to the open consultant areas, where they were assisted. While I continued waiting, approximately four customers who had been behind me were assisted before me. After waiting for another 25 minutes, I approached the consultant and asked about being assisted. To my frustration, he told me that I needed to wait because he was going to assist a customer who had just walked in to open a new account. At this point, I was extremely disappointed and frustrated. I had already spent almost an hour at the branch without receiving any assistance, despite initially being next in line and being specifically told that the consultant would assist me. This experience was unacceptable and demonstrated a serious lack of customer service, queue management and consideration for customers who had been waiting. I would appreciate an explanation as to why I was repeatedly overlooked and why customers who arrived after me were prioritised. I request that this complaint be investigated and that appropriate action be taken to prevent other customers from experiencing the same treatment.
