Bajaj Finance - Regarding Loan interest rate and tenure reduction

Dear Sir/Madam,

My Loan No. P***PTP*******.
The executive called me and said that I have sanctioned a pre-approved loan of Rs. *,**,***/-. so that I accepted. Later I got a call from another executive, for documents and he explained the loan details. He said that Loan will be disbursed in full and the interest is *.** per month and the tenure is * years and I accepted and submitted documents. The next day he called and asked me to open the loan agreement link and asked me to click accept and proceed options. He was not given time to read the agreement, I thought he may have mentioned the details of what he promised me. Hence I accepted the agreement. Once the loan amount was disbursed I came to know the amount was sanctioned to me is *,**,***/-, but the loan disbursed *,**,***/-, interest rate **% per annum, tenure * years. almost *****/- deductions for * insurance, breakup period interest and processing fees.
later I requested them to cancel both insurance. They cancelled and adjusted the amount towards the loan as a part payment and I Informed them what they promised before loan disbursement regarding interest and tenure and asked them to make changes in interest rate and tenure. but they did not agree and they tried to convince me.

I don't know why they don't keep their words.

It's my humble request to you to resolve this issue. please reduce interest and tenure as they promised.

Thanks and Regards,
Prathibha Kumari
