pick and pay staff to lax and don't care attitude

i am a regular patron of the pick and pay store in value centre as well as hyper by the sea in durban . i noticed that every time i visit these stores that the staff in particular cashiers are very lax and can't even be bothered about customer service .the ques are always building up out of control ,while cashiers are busy talking in an extremely loud manner .the floor supervisor is never to be seen ,and if there is some situation that requires authorisation ,one would have to wait in excess of 20 min for supervisor to come and resolve .i did speak to both store managers on numerous occasions ,but the problem seems to persist .i advise all patrons to shop at other stores with better customer service ,and stores which thrive on customer satisfaction .
