No contact through Nedbank contact centre

I called Nedbank credit card division on Monday to confirm travel insurance as I booked a flight using my card. I was told, after holding for 20 minutes, that they were too busy to take calls and should leave my details and would receive a call back within an hour. This did not happen. I then emailed the contact centre to be told I should phone.

I also noticed that I have been charged finance charges on my credit card statement when I pay in excess of the full amount owing every month. I really do not understand!

This is not cool Nedbank
