Bajaj Finserv — Fraud from bajaj finserv personal loan agent

Address:	560013
Website:	www.bajajfinserv.in

I had applied for a personal loan in bajaj Finserv. At the time of approval, i was told that the interest rate is 14.5% for 5 years for the amount of 3, 10, 000.
And they took blank cheque's and then they have processed my load at 24.33% rate of interest without even informing me of that and have credited to my account.
Please be aware of such fraud people like Naveen (+91 [protected]) and please don't give away your blank cheque's unless they confirm you by written the Rate of interest.
I'm clueless as to what to do now. I have submitted a complaint in Bajaj Finance site. Waiting to see if they can take any legal actions against such people.
