Bajaj Finserv — Uninformed & Hidden Charges

I have been charged Rs 4999 as a credit vidya fee while i have opted for Flexi Loan. I was never told about the charges and nobody from Bajaj is really helping into this. The only thing they are saying is you have to pay this. Why i have to pay for something which is not required? In total they have charged
Rs 4999 as flexi fee
Rs 4999 as credit vidya fee
Rs 3274 Processing fee and
Rs 50 as stamp fee.

Customer care is not at all helpful and is saying you have to pay for this.
I only required a loan of 65K and they gave me this flexi loan saying as the best option and now i have to pay my 65K + interest + per month flexi fee + 13000 fee.

My Loan Account number is : P401PSP3020734
