Instead we find ourselves here. I'm sorry that you feel so let down by the process, and I realise that you feel you've followed the right process. But fundamentally you've assumed malice where there was in fact a simple error. Had you taken a few minutes to check before doing this, we'd all have been better off.
Having said all that, we obviously need a more clearly documented "what to do when you don't get a reply" policy. We also need to move the email.
