Customer service very poor

i received one of the worst service bad bad bad bad bad completely worst service and one of the worst service at game the service was the worst. I went to game jubille mall 11th of August 2018 to buy groceries and i had the trolley with me and i paid for my stuff and i went to other stores to buy.Because the stores dont allow us to get in the shop with groceries i took my plastics to spar parcel counter and went inside the store to compare prices and i didn't get what i wanted so i decided to go back to game and get what iwas looking for,i didn't take my plastics because game and spar are not far from each other so i dediced to go with the trolley at game and was gonna go back and pick up my plastics at spar.I went to game with the trolley to buy soft drinks and came out with only 1 drink and the secuirty stopped me telling me that i can't come out with the trolly cause i only bought one item and i told them that i came back earlier to buy groceries and they are at spar parcel counter cause i wanted to avoid packing and upacking stuff when i get in the store cause i have sensitive items in the plastics since stores doesn't allow us to shop around with our plastics we must always put them in the parcel counter.I explained my situation and the security refused to understand my situation and they kept on insisting that i won't leave with the trolley to spar , since i was not winning i told them i will leave the trolley and drink with them to pick my plastic bags which are heavy and i have asthma i can't hold heavy stuff for long i called asking to speak to the managerr but he was pathetic he could'nt help he told me he can't do anything about it i must do as security guys are telling me.I deserve a public apology from the humiliation that i receided from the staff,employees and manager of game the service and treatment they game gave me was inhuman .I don't understand why malls in black communities don't value us as customers the kind of service i received was pathetic,after struggling with the plastics from spar and not getting help from the manager at game i went with my plastics to get the trolley which they decided to give to someone while i was coming to the entrance i asked them why they did that but they could't answer me ,the service and treatment was humiliating,from the treatment i received i believe that the employees must get warning and apologise to me personally ,i am not sure if i will ever go to GAME JUBILLE MALL EVER AGAIN .I NEED A PROPER APOLOGY FROM THE PEOPLE THAT GAVE ME THE TREATMENT THAT I EXPERIENCED.
