Bad customer service

Good day I was in Pick n Pay Protea Glen waiting in a queue while one of your staff member was busy helping me with a price on one of your liquor items when the Supervisor by the name of Moleboheng just came and closed the till without communicating with me as a customer as I was already on the queue and her attitude was terrible I then reported this to the store manager who didn't even seem to care as he did not addressed the matter at all but was mostly sitting and said oh I know about the complaint, As a customer I feel that I could have been given a better treatment in this store and would like feedback on this matter as I feel that customer service doesn't exist at all in this branch
