Pick n pay delmas deli poor customer service

Hi I'm a very angry customer. I went to pick n pay delmas today morning at the deli.i wanted to place an order the was a guy who works at the deli by the name of Melusi he didn't greet me or say anything to me then the supervisor saw that I was not assisted she then came to me I told her what I wanted and then she told him to assist me hes response was he will never do that in front of me and he's supervisor. I want him to be disciplined and be taught what customer service is.
