Same thing happened in one of my accounts.
They tried to debit thrice and one got succesful then they two times credited 209916 so I got 400k + in my account and again they debited 209916 twice .So now everything is okay :)
Really disappoining work from Kfintech.
It went smooth as first they credited then they debited.It is the most strange thing happened in my IPO career.
Just check the transaction they made in my account.sharing a photo just look into it😅
