Bajaj Finance — Not getting response to close the personal loan

Address:	500007
Website:	www.bajajfinserv.in

I have taken the personal loan, while offering the loan it is clearly mentioned to me that there wont be any foreclosure charges / part payment charges, but later I got an email saying they are changing the terms and conditions and I will be applied with charges.
Is this how a company works? If I say my financial stability is not good so I dont pay the EMI, will you accept?

I am trying to contact the Bajaj since June 11th, till now I didn't get proper response.

I want the problem to be resolved ASAP.

Thanks,
Gopi.
