Wesbank not cutting interest on early vehicle sett

As 'n single lady I got a good deal form Wesbank vehicle finance two years ago, so I financed my vehicle with them, now I am looking at a trade in, and they do not want to set me free of three years of interest, Asked for settlement, witch is now almost seven thousand rand more than statement. And they keep their correspondence that they may do this. Is there now way, I have had vehicles before, and no bank ever did this, they say it's all penalty. absurd,<br> <br> BE AWARE, OF THIS PERFECT CUSTOMER BUSINESS OF THEM, THEY SO DO HELP CONSUMERS WITH THIS CATCH. YOU GO WESBANK.
