Bajaj Finserv — difference in emi amount of personal loan

Address:

Bangalore, Karnataka, 560068

I am a old customer having bajaj emi card. Very recent i got a call from your lending department i got a pre-approved loan of 3.4l at an interest rate of 10.47%, processing fees 10800+gst, and stamp duty of 500.
The emi amount which they told and informed is rs7618 per month. When i check with emi calculator actual emi at the rate of 10.47% is rs6444, which cost me burden of 70-80 thousand rupees.
Please look into it on priority and respond me at the earliest.

No of your customer services help me out
My issue. Your company's customer service is very poor.
