Unhappy, upset client

HI. Clicks should train their management that thinks they own the stores how to interact with customers. I went to Clicks as i always do on a regular base for all my needs that i always buy there,Airport Mall, Belhar, and management felt its appropriate that i leave my personal belongings in a trolley with the security which dont even watch the trolley at all. Why should a customer do that. Was it because i am coloured and the security and management is black ? I am very upset with their behaviour. I demand that they give me an apology. I can also give my reward card number so they can check how a loyal customer i am.. This is the store nearest to me as i also work in the mall at another store and for me its convenient as to go in my lunch or just after work to go do my business. But i feel to rather go to stores where you dont get treated as a *****. I will find out what the managers name is as i was too furious to ask at that moment as i walked out of that store immediately. Please train your management and securities accordingly. Thanks
