I first requested for limit enhancement but they said to send the documents by courier or drop them in the branch. But I yelled at them that
We're in 2023 and you're still asking me send something by post. This seems like hdfc is outdated. This is very shame. Do hdfc know something about technology?
I can also attach those documents and mail you digitally. What's wrong in digital documents?
But they said due to security, they asked to send.
Then again they sent a mail to send my payslips over the email. So I have shared them. They asked a few days to review. They offered extra limit then.
