No Service when most needed

I had to cancel My credit card on the 15th of this month because of *****. I was told a new one would be delivered to me within 5-7 working days and the R159 F2F courier charge was debited on the 17th. As of this moment I am still waiting for the card and have not even been contacted by the Courier. I have also spent almost 2hrs on my phone trying to get past the 'we are experiencing high call volumes' . This currently at 23 minutes , even though I phoned the second the opened for 'Business'? I hesitate to call it that.
