What would you do?

HS game:

I at the C position. White 23 drives the lane in my PCA. I am referring the defense. Blue 11 has a legal guarding position and gets plowed over. I blow my whistle and look across the key and the 'L' has a whistle. I make eye contact with him and wait. The game is at stand still. I waited about a second (so it seems). I call the charge. White coach is upset, yada yada yada.

At half time, as soon as we get in the locker room, that same official gets in my face telling me that I was out of position, it was his primary, and I didn't even look at him. I said I waited to see what you had. He said that he had a foul on the arm. I told him that blue 11 had legal guarding position. AT that time he calls me a liar.

What would you do now?
