Bank Issue - Selling Block

Is it true? that the broker is telling to me that my bank details are incorrect and that the quaterly settlement & payouts are rejected so they block my share for sell from DP!

Do check what details you have given. Sometimes, when you give your account number, one digit could go missing . If this is the case, the transactions would be rejected. Double check the account number and IFSC code (if they have asked for the same)

which broker is telling you that?
