searched for customer sevice complaint

1 cashier at express tills, which told me to go to another till as she was the only one open. Other cashier informed me her till was not working which is not my problem. Then proceeded to collect my coffee at other entrance and sensormatics beeped as I had soft tag in my jacket pocket from my retail store.security stopped me and asked why the machine beeped as if its my duty to explain how to do his job. Went to see manger who I waited 10 min for then searched my jacket and disregarded any complaint I had about the service I received from his employees. This was done at the front of the store for all customers to see checked my receipt as if I was a ***** and half hearted apologised like all it was about was me making the sensormatics beep. So embarrassed and upset not giving a damn about the blatant disregard for customer service I left the store feeling nothing but anger and disappointment for wasting my time at even bothering to complain to the manger. That is a tourist destination mall I would hate to think the bad name Cape Town gets for their lack of competence. Thanks for treating me like a ***** pick n pay.
