Bad Service

Went to Pick n Pay Dobsonville Ext 3 on the 03/03. I requested to speak to a Supervisor,cause the queue was long. I dealt with Rambo who said I should wait for my turn to come before he calls the Supervisor rudely. I waited patiently for my turn,however he told me that I should've asked someone for assistance. Reason why I needed the Supervisor is to assist with the queue as there were senior citizens due to being month end. Supervisor came through he tried to resolve the matter however Rambo was Rambo. Pls assist I'm shocked as customers were disappointed about the service received, the store needs training cause this is not the 1st incident. Supervisor will confirm what went down on that day,this happened at the butcher department. Need response ASAP.
