Retrieveval of documents

I have spend hours on the phone trying to get through to wesbank, when you finally speak to someone on the other side they are very *********** and not able to help you, then they put you through to someone else and they cant help you, then they put you through to someone else and they cant help you and on and on it goes. I also tried emailing to no avail. i have account inquiries and i am waiting on my NATIS documents on vehicle settlement, vehicles that i need to sell urgently but cant without the papers.
