Bajaj Finserv — excess process fee amount deducted and interest rate deduction for non utilized amount

I has applied for flexi loan and loan was sanctioned saying 2% proceess fee will be deducted which includes all by a representative named parminder. When loan sanctioned excess amount was deducted hence i contacted her about this she assured she will speak about this to her manager. Now she is saying i need to speak about this bajaj finserve. She works for flexiserviceteam i believe. Through her my loan got processed. There was an excess amount of 2651/- inr is deducted and when loan got processed i was not informed about the handling of account by the representative in time and hence all amount was credited to my account instead of virtual bajaj account. Hence an interest amount of 3567/- inr is deducted without me being utilized any amount. I tried to compalint about this to the representative in contact from bajaj finserve and he told due to covid all offices were closed he is unable to help me. He provided an email with spelling mistake with it due to which all email sent to bajaj customer care bounce back. Kindly look in to my grievance and help to resolve the issue with the company or personnel. I am having all the chat details and call details as evidence.
