Lack of customer service

I was embarrassed by a very unprofessional Agnes Mulauzi today just now in fact. I am like any other consumer there waiting in line to pay for items I just bought, infront of that queue two young ladies have come across a problem with their transaction their card has a daily limit of a thousand to swipe. The problem took sometime and I am noticing that because we not moving then I ask a teller once I saw that to tell is what's wrong and she explains what I've shared above the two ladies. Now we wait for a solution mind you no has informed us what's going on we had to fend for ourselves, we decided to just rather go and move to another POS and that's just where Agnes comes in as soon as we move she attends to the previous till no apology to the consumers who are still hoping that the matter is resolved. She then suggests that the ladies can do a cash back at our till the one we just moved to she doesn't explain nothing she goes right ahead and forces the till operator Nthabiseng who was not condoning the action but I don't think she had a choice or whatsoever she's being intimidated by this lady Agnes. Agnes talks back passively after I have complained that they can't just act as if we are not there she rants from the end side of the till, the two young ladies yes they were assisted but about me and the rest of the people being treated as if we don't exist in front of this lady`s ******** behavior. I am not impressed.
