Nedbank revealing account details and passwords.

Good day, I just received an email from Nedbank, stating what my password is in the subject line. The email which I tried with fail to report on the Nedbank online complaints section twice was rejected. The online Nedbank form took all my personal details - more than usual and then paused and rejected my complaint form. The email details things about my account which never usually happens, displaying the kind of bank account I have and a good portion of my password. Since when does a bank throw those details in an email subject line for all to see.
