Standard Bank - No response on potential phishing

I have received 2 emails (from what appears to be a legitimate email address), supposedly with a statement from Standard Bank. I do not have an account with them.

This means one of 2 things. Either it's a phishing expedition by a hacker, or I have been sent the email by Standard Bank in error.

As such, I emailed Standard Bank, querying the above. No response to either of my emails from them.

In a time where cyber-attacks are on the increase, Standard Bank should at least have the courtesy to take the time to investigate and investigate.
