Oriental Bank Of Commerce — reduction of emi

Address:

Kolkata, West Bengal, 700157

Dear sir,
My education loan rate of interest has reduced to 10.25%.
My loan amount is rs.750000.
As per your bank emi calculator, my emi should come to rs.12494 for 7 years.
But as per your system i have to pay rs 13494 every month as emi.
Why i am paying rs.[protected]=rs.1000 extra emi every month?
I dont want to extend the tenure but kindly reduce the my emi to rs.12494 on priority basis.
Immediate action shall be highly appreciated.
