As per your query the loan amount was Rs. 389,000- which means bank might have given it without any security. However, Bank must have included our father/mother as joing borrower. You say you do not have job. What about the joint borrower?
Having taken a loan from bank at concessional simple rate of interest till completion of your studies and later on with compound interest, it is your bounden duty to pay the loan. You may approach Bank branch with Rs.200,000 and tell them to rephase the loan after accepting the amount. Since the balance amount shall come down drastically (by your paying Rs.200,000), balance repayment instalment shall be reduced. If branch is not cooperative, you may write suitably to their Regional Office to help you in the matter.
