Bajaj Finserv — Complaining regarding mndt charges 118 and foreclosure information given incorrectly

I have taken Overdraft facility from bajaj finserve. They provide me with 560000 amount of loan, however I use only 60000 and rest I paid back to OD account. In one month I paid them back my all loan. When I want to foreclose the account that time my agent who gave me loan is telling that I have to pay 4 % charges almost 27000.. previously he didn't told me this things..when I particularly ask about foreclose, he said no extra charges for foreclose. Secondly they also cut my 118rupees directly from my account.
