Inefficient customer service

I am appalled in the way Mr Price Centurion Mall treat their clients, they are disorganised and not customer orientated, On Monday 26th of October went in to the store to buy an item stood in line oblivious to the fact that the store system was off line, then I heard one of the cashiers asked Junior (Team Leader) to inform the clients that the systems are off line and she blatantly refused, she will not do it. A gentleman came in from I assumed the floor and spoke on to the intercom and informed us that they are offline and we should bear with them, and it was almost closing time,asked if they could keep the item until I come back and fetch it, on Wednesday I went back, though I had written my name on the package it was no where to be find Junior suggested that I go back to the floor and look for another item similar to the one I had asked them to keep it was clear they misplaced it, NICE, did exactly that, had another request 02/11/2015 and got a stinking attitude from one Kgadi Rangata (the name on the slip) and its not that I was being impossible, but she could have been friendly. I am very disappointed. Junior is a bad example of a leader, how will the others learn from her.
