embarrassing and humiliating

I visited Mr Price Home in Mall of the South on the 3rd May 2019 in the Morning, firstly the operating hours show that the store opens at 09:00 but at 09:00 the store was not open, I went in the store to exchange the item I received as a gift, when I entered the store I was the first customer and found Segeru Mabitsela he was still opening the door which makes a sound when opening it. looked around the store and did not find anything I could exchange my gift with. When I was walking out the store there was s peeping sound I went out and at that time the were now other customers in the store and to my surprise I was accused of theft. The most embarrassing and humiliating moment in my life I went back in the store and Segeru Mabitsela acccused me of *****ing the item which I went into the store with he called other lady and told that lady that he saw me taking the item I asked him twice and he said yes he saw me take the item. We all went to the pay point and other lady said yes I stole as there are the only ones who pack the items liked that. the Store Manager Sophie Masangane also confirmed Mall of the South is the only store that packs that item like that I told every one that it was a birthday gift I told them where the item was bought I even told them the date when it was bought, even told them what else was bought on that date. I even asked the store manager to check the CCTV footage and she told me they CAN"T Check anything, I was told to leave the item I bought in the store and continue with my shopping the only person who believed me and came up with a solution was the 2IC Sel**** Ikanery she called Sandton city where the item was bought she even gave me her mobile phone to call the person who bought me the item and we asked for the slip to be send to her. I'm highly disappointment in Mr Price Home Mall of the South for calling me a theft, the thing that annoys me even more is that the day I was accused of theft was the day before my engagement party They ruined the precious moment for me and that will always leave a mark and a bad taste in my month. I was so annoyed I ended up not even taking the item back, how can you take something back after you where accused of theft. I what steps to be taken against Segeru Mabitsela for calling me a theft. I was shocked that only one person in the store knew and understood TCF, you don't accuse someone of something you don't have proof for. This Segeru Mabitsela guy even told me that when the check the stock the item I have confirms that the store had 4 items and mine was the 4th one, the even said where the items were packed he can see that one item is missing because I STOLE one.
