Disappointing service from Nedbank

Where do I begin... I'm very disappointed in the service received from Nedbanks credit card division. I app**** for a credit card close to 3 weeks ago, it was provisionally approved. They requested documents that I sent immediately and received a text a few hours later stating that they have been received. A week later I get a call from the department asking me to send my documents, I explained that the documents were sent and I was told that they are having a problem with their servers. Granted, I understood. I resent them. Just last week I received a call again and was asked again to send my documents, this time to a personal email, of which I did. I've been told my application has been sent in for verification. How long does verification take and do we not get updates or something. This is poor service and I'm really disappointed. If the application is unsuccessful I should be made aware so that I can go to another bank. It seems is difficult to get an answer even after 3 weeks.
