Poor customer service

Early this morning we were waiting to use the ATMs for quite some time. As we were waiting there was a gentleman that was struggling to use the machine for whatever services he needed. So we then asked the guard on duty to assist, he rudely refused. Then we asked a guy by the name of Mxolisi Ngcobo to assist us he then told us those are self service machines customers SHOULD know how to use them. We then expressed that the man there has been struggling for quite a bit however he dismissed us and told us that he has no business assisting customers because it has nothing to do with him. On top of telling us that it is pointless for customers to go inside the bank because he’ll be taken out to the atm regardless. I found that very rude and uncanny because he works to make sure customers are satisfied with whatever services they require.
