When it rains it pours (especially with the weather we have been having lately)

Um, so today was my first day at my new job and I love it. However, I check my voicemail when I get out of the office and I have a voicemail from PRIMEX (the Concord job I have been WAITING to hear from)... They want 3 letters of reference... I haven't heard JACK from them in over 2 weeks and the DAY I start my new, fantastic job (that fills me w/ happiness) THEY CALL? What is this all about?
