Humiliation and disgust

I am so disgusted with the service I received at Daku spar this morning, Customer service is horrible and unfortunately that is where I do my shopping and their service is disgusting. Today I could hear there's commotion and one lady who stood at the door checking slips yelled in her louded voice afar Hey Sisi no night dresses are allowed in there store, everyone was looking around me included, so I was like they are definitely not speaking to me because I'm wearing a normal dress which I bought from Pick n Pay clothing. one guy came running to me and said night dresses are not allowed when he came closer, he realised its actually a dress, Me still being lost this lady at the door yelled again no night dresses looking at me directly now she then realised its actually a dress and went back to the door no apology nothing, there was another lady standing besides the till I thought she was a packer she just stood there and said nothing. anyway I asked for the manager the cashier said He's on the floor and said but there's the supervisor, pointing at the lady whom I thought was a packer who stood there said nothing while all this was happening. I then went to her as She moved and stood at the Kiosk I asked her to please get me a manager and she said he's coming in only at 08:00. I told her the reason I want a manager even though she was also there. I expressed my frustration to her and she was like I am apologizing moss what do you want me to do? I then went out gave my slip to the lady who was yelling at the door, I asked her was it you who was yelling at me and the only thing she said jha! I was also told by a cashier. My experience at that Spar was very horrible and I am so frustrated
