Worst Service Ever

Good Day I would like to lodge a Complaint in regards to the service that I am getting from the Nedbank contact centre & Card Division. This Morning around 08:00 AM I called DSV to track My Credit Card, They advised me to contact Nedbank because there are outstanding documents that need to be sent through them before they can deliver the Credit Card to me. I called Nedbank Contact centre on *** Number and I was assisted by the Agent Named Mthoko, He said he will send an email to the card division so that they could forward the documents to me. He estimated that the process could take up to 3 Working Days. I said to him I can not wait for more Days because my application has been pending for over 3 Weeks now, I told him that I need to speak to his superior. I was kept holding for more than 15 minutes then he told me that His Manager will contact me back because he is caught up with some duties. As I am typing this Email, No one has contacted me yet and I do not know what is really happening with My Credit Card. Is this the way that you are treating your customer? 3 Weeks of waiting for a credit Card and nothing is really happening. I am extremely Disappointed with the service that I am getting from Nedbank Regards
