Rude manager and staff

Mr Price highveld has a very rude and very unprofessional store manager. I went to the store with my sister who was heavily pregnant it was just after the president unlocked level 4 for pregnant ladies, so my little sister had to get stuff for herself for the hospital i.e ( gown, morning shoes and pyjamas) as she was only left with a week until the arrival of the baby. when we got there the queue was very long and i decided to go to the store manger and asked her politely if pregnant woman stand in those lines to get inside the shop she then responded to me rudely saying " yes they do there's nothing with them" My sister stood in that queue until she couldn't take no more, she decided to go wait in the car and i buy her the stuff cause she felt dizzy and tired. When i finally got inside the shop i video called my sister asking her which gown she'd want or love, one of the staff said to me i hope you fold that gown the same way you found it while i was on the video call with my sister showing her the gown i had on my hand. I feel the staff is bravely rude because they know that even if you report them the manager will not do anything as she is as rude as them. i was very shocked i left the shop immediately and went the Edgars.
