Bad service

I have had the worst experience ever with the Nedbank Bardene branch while doing vehicle finance. It has taken a week and a half to get the deal done, being sent from pillar to post. Up and down for paperwork, that was asked if it's needed on day 1, and then requested on day 3. And this after the application was only submitted 2 days later than I handed it in. Then the banker and branch manager are off to roadshow and the next day(Saturday) also both off......so no feedback or communication able. Even the branch manager said she will call me back with feedback on 2 occasions and still no call too today. I have incurred various costs with regards to time lost, productivity, and costs with insurance, deposits and interest. Very bad for me as I thought this bank will be my choice to run my business account......
