meaningless auth for account

Yesterday I went to purchase some few items at Arkamans apparently when I got to the cashier he said the purchase couldn’t go through because there’s no credit whereas I received a limit of R6450 credit limit and used R4665.85. okay he explained that he had to call the contact centre to find out what the problem was. He gave this other lady the phone, it took her 45min to get assistance from the contact centre, they apparently authorized it and there was like R1700 credit limit available. After so long of waiting when the guy tried to process the purchase it couldn’t go through, and it was already 5:45. On Saturday that was the case when I purchased at mall of Africa, they had to call the contact centre. Cant one just enjoy their shopping without all this meaningless stinking processes. This is pure nonsense struu. I want this sorted today because I’ll be knocking off at 4:30 and I’ll be going back there today and God knows I don’t want to go through this stupid processes of which the cashiers couldn’t understand what was happening I’ve waited long for nothing yestday yeeeer.
