How would you handle this

co-worker's employees write stuff about my area at night. I don't see anything ever written, so I can't resolve problems etc.

Idiot boss questions me and I tell her how am I supposed to resolve issues if I don't know if there is a problem.

So how do I counter act this *******? He's really aggravating the **** out of me

Do I start sending emails to our boss and her boss about his incompitant area?

Really getting tired of the games
