Overdraft Facility - Travel

I have been a Nedbank User for the last 6 years. Recently i app**** for a over draft facility and was asked only for salary slips which i have sent through. After no feedback for 2 weeks i called them and after 3 calls I was advised that they require a letter from my HR department. I have a friend who called in and had her overdraft facility with Nedbank done on the Phone. Why do i get a different approach and then 4 days before i require the Loan you request more info. Disappointed beyond belief and will be looking at another Bank as an option.
