Bad experience at Jabulani branch

This happened a while back on the 7th of October I went to food *****s at the Jabulani Mall branch, it was I think 18:20 or 18:25 I can't remember correctly but it was 10 min before their closing time. Firstly the time on the web is not the same as the actual trading hours, when I checked before I left home it showed that the branch closes at 8pm so I rushed there only to be told by the security that they were closed, I asked to speak to the Manager on duty as I was there 10 minutes before their closing time, at first the security guard told me that he can't let me in to speak to the Manager and he also did not assist in calling the Manager for me as I explained that I only needed beetroot and carrots as we were preparing for my brother's funeral which was the next day on the 8th of October, I even begged them to allow me to ask one customer that was already in to buy the things for me and he refused and asked me why I waited till late to come buy the goods because I knew that I needed those things. The cashier that was working on the till close to the door overheard the conversation and called a lady by the name of Dudu to assist. I am not sure if she was the manager on duty or the supervisor as I was told by the security that there was ko manager on duty that day. She already had an attitude when she came, she did not want to hear what I was saying, she just gave me the look and said she can't assist me and left me standing at the door stranded. I ended up going to another retailer where I got the best service I will never in my whole life set food at food *****s market. I did not want to fight or argue with them because their trading hours were incorrect on their website and the store closed 10 minutes earlier and Dudu has no Managerial skills, she does not have a clue what customer service is
