Worst treatment in the hands of dis-chem security - Consumer Complaint for DIS-CHEM HEAD OFFICE

I was doing shopping at the vaal mall dis-chem at vanderbiljpark and I was in a queue waiting to make payments, before it was my turn to make payments I saw a flavored drinks in a fridge next me,while was taking them out of the fridge the cashier called and my daughter pushed the trolley and head to the cashier and I rushed to them, I made the payment of all the things in my trolley which amounted to R144, but there was a box of Tea amounting to R24 I did not see that was left in my trolley and I left dis-chem and was heading to my car when the security came to me started going through my trolley and out came a box of Tea. He then told me I had to go back to the shop, I agreed thinking he wanted me to make payment for the tea, but God when I got to the dis-chem I was treated like a a serial shop lifter the supervisor of security (I assume) was the rudest person I have ever meet, he taking pictures of me and and shouting at me like some criminal of the street and when he was finished he told me I had to go pay for the tea. I said after how you treat me never I refused, by this time I was talking back to him and he told me I had an attitude and he was going to call the police and get me arrested. All I know is am not spending my money at dis-chem anymore.
