Poor service

I went to Nedbank Woodlands 12 weeks ago to revise homeloan. I was sent from pillar to post. Finally after two weeks I went to sent everything via email back. Since then I sent numerous emails to find out wat was going on...still no reply. I went to Woodlands branch one again, they told me I cant see him without an appointment, which I need to make via email. So, thats what I did!! Still no reply!!!
