APPAULING CUSTOMER SERVICE

I went into the store today during my lunch time which is 45 minutes, after asking for assistance from two different employees i finally got what i wanted. I then went to queue and pay for these two items and as I left the store the detectors went off. Mind you im now rushing to head back to work and the security guard runs after me and starts searching me and i take out the two items from my bag and the slip to now prove I did not ***** these things. She takes my slip leaves me standing there not knowing what is happening and when she gets back she still does not give me any explanation as to why she just started searching me and does not even apologise for treating me like a complete *****. The disrespect from the security guard and everyone at the store for just looking at me as if I'm in the wrong here. Nobody apologised and I feel like my rights were messed with. I will never ever go back to the clicks on the Golden Acre as their are rude, pathetic and inconsiderate employees with no CUSTOMER SERVICE what so ever. I will make sure I tell the world about how supercilious they are.
