Makro credit card collection

I have been waiting for 30 minutes to collect my Makro credit card. Customers in front of me even left. I asked for the managers number and i was shown a lady who has a badge of HR manager who said the lady is helping someone to call head office. When i eventually arrived in front she had an attitude and said im ruining her day. She tells me a different story that the system was offline of which i dont think is true. This is the worst service and customer experience ever! I regret signing up with makro after todays experience. This lady shud be moved to the back she cant deal with customers at all. Then while i wait she says the " numbers dont work", to which i ask what must i do? I am here with someone who doesnt know what to do.....how do u train your people????
