Very poor service

I would like to share my very poor experience with Nedbank to all of er customers. I have been trying since the 20th of December till now to sort out my overdraft facility on my account with absolutely no satisfaction whatsoever from Nedbank. I've been asked 4 times to send my documentation to them which I did. I even went to the branch in Springs Mall to try and sort it out only to be told that "this department is closed for December". I have resent the documents again last week and still have no response from Nedbank. They are very fast to take monthly fees, but absolutely poor in giving the service the promise.. I have been a client of Nedbank for many years and I am considering closing my account with them.
