Take the kids with you. Get this thing done, don't take no for an answer.
When I was a very young boy, my mother found out I wasn't being enrolled into the local kinder. I have no idea why; but at the time, she was a SAHM, my brothers were in school, and my sister was an infant and with a sitter for this event. My Dad was at work and had the family car. I remember walking to that school with my mother who went to fight for my admission. She met with the principal and other administrators for a while. I remember vividly walking back home with her, as she was crying about her experience. But I'll never forget accompanying her while she was going to bat for me.
Maybe this can be such an experience for your kids...seeing Dad, yet again, having to go out of his way to do the right thing for them. Change your perspective...maybe it'll be good for them.
