Have them click all 3 domains and click "cancel transfer".
The give them your Godaddy customer ID number and your email address on file at Godaddy and have him initiate the transfer. Once he's initiated the transfer you should be able to login to Godaddy here: https://dcc.godaddy.com/transfers/in
Click on all 3 domains and on the menu above the list click on "accept." Let me know if that works.
