Customer care line deems my query as NOT URGENT- Disgusting Customer Service!

I recently app**** online for a Nedbank credit card (and was approved). On my application I indicated that I would be paying through a debit order monthly on the 25th as it is the day in which I get my salary. I went to fetch the card from a branch and the consultant who helped also confirmed my repayment arrangement. Little did I know that the contract document that she printed for me to sign had 2 different dates, i.e. 1 for the 17th monthly (on page 1) and another for the 25th (on page 2). Of course the 17th June came and the deduction from Nedbank took place. I went to the branch for assistance and on the 2 occasions I was there, there was a problem with the system- so I could not be helped. I then called the call centre on Monday the 12th July- and because of the riots, lootings and everything else that was going on the country (KZN & Gauteng), my request to get assistance from by the call centre was deemed "NOT URGENT". In spite of my protest with the consultant (Tseleng) who apparently had to consult with her manager for me to get assisted, she eventually promised to call me back the next day (Tuesday) [probably to help me??]. It is Tuesday as I write this down and the violence and lootings are continuing, thus it means my "NOT URGENT" query will remain that - "NOT URGENT". What kind of customer service is this where a client is told point blank that your query is NOT URGENT? What must I do because in my opinion, my query is URGENT otherwise I would not have called, spent my airtime and time holding the line ONLY to be told that my query is NOT URGENT. This is TOTALLY UNACCEPTABLE and I wonder how Nedbank can really justify not assisting their clients (UNLESS THEY DO NOT VALUE THEM) because of riots which are not happening ONLINE as if helping clients will WASTE their VALUABLE time with their VALUABLE CLIENTS WHO HAVE URGENT ISSUES. VERY DISGUSTING AND DISAPPOINTING CUSTOMER SERVICE- SHAME ON YOU NEDBANK FOR MAKING ME FEEL LESS OF A CLIENT IN YOUR ORGANISATION!
