Bajaj Finserv — Uninformed about Credit Vidya Fee by agent

I have recently taken Bajaj Flexi loan. I was charged "Credit Vidya Fee". But during numerous calls with the sales agent before loan approval, she never mentioned anything about "Credit Vidya Fee". This clearly indicates baiting consumers with opportunistic behaviour based on lying by omission. Please refund the amount Rs4999 which was charged without educating the consumer about the details of the plan.
I am attaching an email screenshot which contains the agent's proposal containing all possible fee that I was going to be charged(highlighted in yellow). It clearly doesn't contain any information about Credit Vidya Fee
