Nedbank. What are you doing?

So I have a personal account which I never actually signed for. It was a SAA Voyager credit card which became obsolete.. now I have Nedbank credit card and greenbacks but I have actually never signed anything. Yesterday I opened up a small business account which had been opened but no contracts or and paperwork at all. Was expecting a call from my relationship manager. Nothing. I try to call and get a number not reachable. What am I doing wrong?
