Ya ever hit the wrong button while listening to your voicemail, and accidentally delete a message?
I did that this morning. And our dufus voicemail system does not allow you to retrieve a message you've deleted, even if you pressed the delete key mere seconds before. It doesn't even help to yell at it.
So ... if you called me sometime within the last day or so, and I have not returned the call, holler at me again, please.
