Poor Feedback

I called Nedbank a week ago quering an account of mine. I was told that this was closed however over a year later it has not been updated on transunion. I was told to send through my report and they would clear it in 7 days. Its a week now and it still hasnt been cleared. The biggest issue is i am not even getting any feedback from the person who assisted me. This is not on. It doesnt take much to atleast send an email about things that affact other peoples lives.
