Indian Overseas Bank — Reg:Educational Loan

Hi sir, This is regarding Educational Loan, I have completed my B.e in 2012 and I got a reasonable salary now only. Myself and my sister got loan from Indian Overseas bank Srinivasanagar Branch. Since i didnt have job i paid interest and closed my sister Loan Amount Last 4 Months before. Then i started paying Interest for my Loan 5000Rs Per Month. Loan Amount I got Rs.2, 00, 000(1, 50, 000+Interest). I visited the bank and had a speech with Assistant Manager and started paying 5000rs\month. Today the Bank Manager called to my mom and spoken with abusive words. He says that the Loan is provide by his Own Money. I didnt say i will not pay my loan. I am paying what i am getting and I told as soon as possible i Will Close It. I need Higher Authorities to take action on the Srinivasanagar IOB bank Manager. Thanks for your understanding.
