HDFC Bank — Low severity memo present on debit account

This is regarding my HDFC account being locked from the past 3-4 weeks. After login into Net-banking, I’m not able to perform any transaction, even not able to see the statement. It's showing error "There is a low severity memo present on the debit account. There is a low severity memo present on the Debit account. There is a memo present on the Debit account."
