Child Support & Custody Support Group
This community is dedicated to those involved in child support and custody cases. There are a myriad of challenges involved in any case and this is a safe place to talk about what you're going through with others who may be going through the same. Join the group and seek advice, find or provide a listening ear, or just share your feelings in this support group.
For now, I'd enjoy your vacation, keep making the calls and document the number of times that you've tried to call but haven't gotten through.
Is there anything set up for emergency contact? If so, then go through that channel. It's possible that his cell phone was lost, stolen, whatever (similar, although different issues can come up with house phones).
