Bad customer service

I went to Foschini in town , I met or was served by a guy called Yamnkelani . He is very rude and knows about customer excellence . When I told him that I don’t appreciate the way he speaks to me he told me that I’ve frustrated and mustn’t take it out on him . The store was full of customers . I am so angry for it’s not my first time encountering from Foschini and will make sure that this goes viral . He told me that if I want to report him I must do it he doesn’t care and my complaint will be ignored anyway . This is the foschini I’m golden acre on the second floor …. I came to buy here and he serves me with poor customer service and swears at me
