Not a happy customer at all

The lady seems to be a manager in Cape Gate branch was so rude and mean.i went to fetch my card at Cape gate branch with my 1year boy.my child was just playing around and she said I must stop him from making noise because other people are here to do their banking.i was like WOW ..so I am not here to also do my banking!! For god sake how do I stop a child from playing and making bubbles...do I put my hand on his mouth!!. I was going to understand if the child was crying.i had to leave the branch without finishing what I was doing because of her..I am moving to another bank after using fnb for more than 20 years because of her.
