Pathetic Customer Service

So today was day number 5 awaiting the response on my store card application. When I phoned on the (26/01/16) I was promised by the Manager that a feedback call will be received on the process of the card, yet I had to go into store today after taking the high road and applying online myself to activate the card. With that said it took RCS 15min to process(WONDERFUL TIME RESPONSE) my request! Get to the store and I get assisted by one lady and Pamela - ( the lady who initially assisted with the application on the 22/01/16) their response was the systems are offline and they can't process my application after I've shown emails of approval and smses. No Manager or Assistant manager did the effort to sort out technical difficulties whatsoever. I really won't even do the effort to go back to the store ever.
