The consultant/supervisor was so rude

I went to ackermans in boulders Midrand to do an exchange the treatment I got was so undermining,the lady who was assisting me was so rude to me I felt naked ,my concern is if she was not gonna be able to assist me she should have said so instead of shouting at me as if I was my 2yr old child, I couldn't even answer her because wow she was having me for lunch or it was breakfast I don't know,if she explained to me she won't take the shoes because my toddler had worn them to fit ,I would have understood instead of telling me that I'm scared of my child and I should have let my child cry,if she knows that much about kids I think she was supposed to be a teacher instead of customer servicing personnel,I ended up leaving the shop without even doing what I needed to do. I always buy my baby's stuff at ackermans but the service I got today from that lady I think I need to close my account there.
