Bad customer service

i went to pick n pay @ Chris Hani crossing to claim my lottery winnings but the cashier (Sibongile) at the kiosk pretended not to acknowledge my presence for almost 20 minutes chit chatting with her two other colleagues I've worked in retail that is not customer service when I asked her if she knew who was working at the lottery desk she raised her voice at me and responded with a very bad attitude telling me that she owns the whole kiosk and why didn't I ask her before going to that section I've never received such a service in retail before very disappointed with her service
