Modifying your IPO application

I have cancelled my IPO order. When will my amount get unblocked?

How do I cancel my IPO bid?

I did not receive a payment request, so I have placed another bid. Will the amoutn get blocked twice?

I have added an incorrect UPI Id to my IPO bid, can I correct it?

I don't want to use this UPI id for placing my IPO bid, can I change to another one?
