Canara Bank — EL loan- ASK EXTRA MONEY

Dear sir,
i got educational loan on 2009. Based on OTS i paid full amount to related branch. But still my loan account is not closed & still am not get NOC from bank. Also still i got massage & call from canara bank staff due to loan due pending. from last one around 10 times i discuss with branch manager about loan account closing status, from canara bank side i am not get proper response. also i ask so many times through mail.
So finally my father Mr kolangiyappan discussed with branch manager(Mr obul reddy) on date[protected]. as per discussion Bank manager asked please give Rs 10, 000 (ten thousand rupees) hot case (in hand) with in 2 hours, otherwise you need to pay balance all amount & your OTS amount not considered in final one time settelement.
Am not understand your bank rule. because bank manager told at the time of OTS, this is final settlement no need to pay any amount in feature.
KIndly support me.
