Just give them your name and jury information (I don't remember off hand what is on the summons sheet). Tell them that you have been summoned for jury selection on Monday, but that you would like to know if you have been excused from it and if they can call you.
It is very nerve wreaking !! I was a walking mess. They have no clue what we are up against having to do this. I truly wish you all the best and hope to GOD you are excused again. Let me know how it goes.
