Bajaj Finance — Additional charges on foreclosing personal loan

Address:

Mumbai City, Maharashtra, 500040

Hi Sir,

My Bajaj Finanace Loan account number 400CSP03328533
As per agreement There should be no Foreclosure Charges after 1 year.
But even after two and half yeas, r when I foreclosed loan, They charged me 4 % Charges.
and also I paid all my EMIs without fail on 5 the of every month, As per agreement I should get 1% refund of interest amount, but they refuse to pay as per agreement.
Please resolve this issue.
Thanks
Sudhakar.
