AAAAARRRRGGGHH!!!!!!!!!

I just got home from work around 3:30 and I checked the new and old messages on the house answering machine. The fourth old message was from Kelly, from Human Resources at Burbank Unified School District. She called to tell me the appointment for my test for the job was at 1:30 on Wednesday, September 6th. AARGH! I didn't get the message till Wednesday, September 6th at 3:30, two hours after I was supposed to take the test! I checked the caller ID on the phone, and the message was left on Friday, September 1st, at 4:44 PM. Why didn't I checked the old messages sooner? Now the other question is... who checked the messages in the first place and didn't TELL me I had a message?
