Bad customer service

The whole on a busy saturday with only 2 cashiers operating pay points. We stood there and tolerated this pethetic customer service because we had no choice. How can big store and brand like edcon operate like this. I personally phoned the store while i was queueing to speak to the store manager and the phone was answered by Mmathapelo whom advised that she was an admin manager, i mentioned our concern of long queue and she just said is it! Nothing was done. The top floor had people seating down packing cosmetics, can't there be a priority between managing the queue and stock. We are even directed to go pay down stairs without even taking into consideration the heavy goods that we bought. Can someone look into running this store in an efficient manner.
