Enable FTP for a suspended account?

One of the website hosted on my WHM contains phishing content, I have suspended the account, but due to suspension the ftp account is also suspended, Now i want to enable only FTP so that my client can remove such stuff. I am using v78.0.23, I searched on forums and found that sign of exclamation (!!) is added in etc/vft/user_account_file, but unfortunately i was unable to find such sign in my case most probably its due to the version issue. On the other hand i found the same signs in etc/shadow file, i have removed the signs but it did not work. Is there any solution to it?
