Bad interest rate - not willing to negotiate.

I tried to assist my sister with buying a car. She received finance through Wesbank Finance Toyota.<br> Unfortunately she was given an interest rate of 14.5% which I felt was still a bit high. When I bought my first car only a few years ago I got an interest rate of 11.5%. Initially Wesbank said 16.5% flux, but the man at the car dealer gave excellent service and phoned the manager of Wesbank and got an interest rate of 11.5 %. Now that is what I call service. <br> I phoned Wesbank this morning who advised that Wesbank Toyota should be able to give a better interest rate and that I should speak with the person dealing with the finance at Toyota directly.<br> I phoned the lady - Fiona who is assisting with the application of Finance. She was extremely rude and said she has been doing her job for 21 years. Well I say 21 years of bad service that is. I know Toyota Wesbank finance can give a better interest rate and I feel a young naive teacher is being taken advantage of. <br> Why would Wesbank not give a better interest rate to this young woman?<br> Is it Wesbank themselves or is it Fiona? I understand it is a few years later but I guarantee that a better interest rate can be given.<br> Dr. Coetzee
