Mistreated and Humiliated

my hurt is so very sore taking the way I was treated yesterday at sunshine cash and carry westgate in rooderport, I went there to take something from someone that as working there as approaching the exit the girl at the gate asked to search my bag,Ok with confidence I give her the bag to search in my hand bag I had a hand lotion and facial wipes,this lady took my lotion and called security that she found lotion in my bag.I explained to this guy that I came with it he can even feel its half.this guy demanded I pay for it or leave it then bring till slip to prove I bought,i tried to explain that I had bought the lotion about a month ago and don't have the slip,....mind you this guy is not even dressed in uniform to be a security he started man handling me and pushing me around infront of every one like I was a crimal,i have never felt so humiliated and embarrassed.I feel this was harassment bcoz even the manager that was called did not know how to handle the matter he was screaming and shouting me infront of every one aswell demanding that I pay for my lotion,,,then they said they called police for me when I refused.The police never came I was kept there in the store until after 7pm when they close.then another manager by the name of Tony said he was not aware of the matter they must let me go...imagine the waste of my time the embarrassment and to be humiliated like that....I feel they could have handled the matter differently maybe call me aside by the office, I even demanded cctv but no I was pushed around and manhandled by their so called security
