If you don't know your phone number, how am I supposed to call you?

I have another interview scheduled for next week (I had one Tuesday in Columbus) and the director of the library who left the message said that she was setting up interviews for Friday, September 9th (when she apparently meant the 29th) and then left the wrong phone number, too. Umm, is it wrong that I find two mistakes like this in the span of a 2-minute answering machine message a little discouraging? In terms of, like, maybe that person isn't the greatest manager and not necessarily someone you'd want to work for... To her credit, though, she was nice when I called her back. After I figured out the correct phone number, that is.
