treating customer unfairly

I app**** for personal loan then I was told i'm approved of R117000.00 though I app**** for R120000.00 so when they told me about the terms and conditions they told me i'm approved for 60 months whilst I requested the term to be 48 months they insisted that they cannot grant me that I can rather settle it before time & the difference between the 48 and 60 months term is R400 .

I have been their customer for over 9 years and I even settled my account before time . they even refused to reduce my interest rate . The lady/consultant who called me told me she's going to send a review to management but after a day the other lady told me it's been declined should I reconsider I must apply again .

After few days I got an email where they wanted to find out why I didn't take the offer I rep**** to them and nothing was done .
