Reserve Bank Of India [RBI] — early closure of loan account + charging extra interest in the name of normal interest collection of rs. 999 for four digit loan amount

Dear sir,
I am nandeesh and a reporter of news paper "voice of vishwa", i was working as a teacher that time, a loan of rs. 1, 70, 000 is availed form sib (Loan acc. No. [protected]), after my resignation i did not give any letter to the sib manager to close my account in short time i. E (18 months) because i started repayment from my pocket. The manager, binuraj, sib, bannimantap, without informing me, took my gratuity amount of rs, 1, 29, 000 directly from the school and put into loan amount.
The loan amount paid from my pocket after resignation + salary deduction from salary till the working days in the school exceeded the loan principle amount of rs. 1, 70, 000 and totally i have paid rs. 1, 93, 593 to the loan account till today and a interest of rs. 23, 593 in excess is collected only in 18 months where as the bank gives a time of 4 years (I. E 48 months - at the rate of 13%) to complete the loan.

Now the manager is showing a balance of four digit amount in the loan account, keep on adding the interest on a monthly basis (As mentioned in the bank statement as normal interest collection rs. 990 per month for only remaining loan amount of four digits. When i visited the bank, the manager escape, telling i know to collect your loan amount from your guaranteers, does not pick the phone.

I have paid more the principle amount and not willing to pay any more interest and there is no answer from the manager about the amount rs. 990 per month (As mentioned in the bank statement as normal interest collection) as interest put for a four digits remaining loan amount and i could not understand the way of interest charged by the sib for only 18 months. The time given by the bank is 4 yrs (48 months) to complete the loan at the rate of 13%.
