never have i heard my bank has no cards for me

So I misplaced my card and needed to access from my money, so I go to grand central as it is behind my office only to get told sorry we dnt have debit cards available, surely with there monthly check some1 must hav seen they are low on cards?why should I be impacted by sum1 not checking up on stock? Coz even if no1 is held responsible for stock surely whoever used the last batch could see there are no more cards and could have ordered more. I'm stil loyal to the nedbank brand but this is making me very doubtful.
