Bajaj Finserv — Approved OverDraft amount deposited into Savings Account - Interest charged till I repay. No virtual Account and IFSC code provided

Hello Team,

After approval of OD from SALARIED FLEXI LOAN - Bajaj Finserv, total OD amount got deposited in my savings account on 1/11/2022. Ideal expectation would be they will create Login ID and password and open an OD account. Now for the whole of total OD amount I need to pay interest in next (1st) EMI. This is very cleverly done by the team. Not at a fair thing thing to a customer.

Till date I didn't receive and virtual Acct and IFSC code so that I can add in to my savings account payee list. Until I add payee, I need to pay the interest.
UPI can be done only 1 Lakhs per day.

Why should I pay the interest charged starting 01/11/2022. Atleast team should consider not to charge interest for first 10 days until Payee gets added.

Need appropriate justice for this.
