Wrong information given to my banker!

I love so many things about FNB, esp their ebucks rewards. I always praise FNB when talking to my friends and colleagues, but this past year has been a disaster. The latest issue is a big one for me. I wanted to free up R2000 in my monthly payments, and asked my banker about refinancing my car which is with VW financial services. I was told I can move the finance to Wesbank and this will free the cash I need. I was even given the steps to follow by my banker. After doing the process, I got told I need to contact the refinance department who then told me, I can't make the switch because they are not allowed to because they are sister companies.

I demand to know who gave my banker the wrong information and how Wesbank plans on resolving this. If they can't resolve this and get there communication right, then I'll be moving my business elsewhere.
