Bajaj Finserv — mis selling of product/wrongful information

Address:

Hyderabad, Andhra Pradesh, 500019

I was directed to bajaj finserv by paisa bazar where i was told by baja finserv they would provide me with a flexi loan/overdraft. My requirement was very simple - i was going to pay off my loan with hdfc bank by taking up a flexi loan from baja finserv which would help me reduce the emi i was paying to hdfc to the most possible extent. The emi i paid to hdfc was 24000 rs inr.
I was told by multiple employees across bajaj finserv that flexi loan is the most suited product - i will only pay the interest and no principle amount will be deducted thus making monthly deduction almost half - 12/13k a month. I have constantly re-verified this and constantly been assured that this is how it will work.
Across various points of processing this loan i found information that was different in the written material and when asked, i was asked to ignore it as they need to present the documents this way but the arrangement is that they will only debit me for the interest value. Now i am being debited for 25300 rs for the first month - may 2019.
I have called the employees and their customer care and the lack of response/ mis information and lack of consistency is appalling. I need to report this institution which is clearing not in alignment with legal practices and is misleading innocent consumers.
