Loan application failed

I applied for a HDFC personal loan for the first time in my life, had to clear a bad debt for my father (paying interest for 3 years).

So I have a pre-approved loan of 30lakhs, and I just needed 5, also had no existing EMI/loan and earn 1.1 LPM, with good CIBIL

I thought I was the perfect candidate for getting a loan, but I was wrong and it is not being sanctioned because I wfh and my physical verification in Office is not possible. (They mentioned the loan will be approved for only 2L at a higher interest rate, I declined)

Never have I thought this would be considered, as this is my first time applying for one, do you think I am missing out on anything?

I don't want to touch my current savings or investments, I want to clear it out by taking a personal loan, I believe saving is tough but repayment is easy.(also saving up for my sister's wedding).

Even this loan will be repaid by my Dad, just that It will be in my name, because he does business so want to save the hassle of paperwork or proofs.

What should I do? Should I approach a different bank? Should I wait for some time so that my cibil doesn't get affected by multiple enquiries
