Pregnant and unfairly treated

I went to pep clothing Signet Lenasia today to pay my dstv account,I'm 8 months pregnant and couldn't stand in the line since it was very long, decided to go to till number 5 the lady who was there was nthabiseng I asked to pay she gave me attitude and told me to go and stand at the back of the line ,I asked for the manager she refused to call her until one of her colleagues told her that she should help me since she can see I'm heavy pregnant,she simply replyed that she wasn't aware and then said she's offline I should go to another store where there's no line😔😥😥
