Unhappy client

I got an sms in the 1st week on the month in August that one of my cards will expire by September and on to receive an sms again on the 30 August to come fetch my card, which for me was very late. On the 3 September , I went to Nedbank, Thabo Sehume Branch in the morning before I get to work to sought out the card issue as I intend using it today still , I was there from 8H15 knowing they open @ 8H30, and only to be told after opening their system is offline, what must I do as Nedbank delayed my cards? I am not happy as I need to use my card. I need the card delivered to me and as it is linked on my profile, and I have the app, then I can activate it my self as I do not see myself going back to he Branch and quee again.
