Did you mention you were injured?  Did you get excused from the event?  Did you tell anyone you weren't coming.

Yeah reddit is full of people who will tell you to report the coach, but if it looked like you were just shirking and being irresponsible, especially if it's not the first time, the coach showing up and being let in by parents isnt wild and outlandish.  It could be concern or firm mentorship, especially if tour parents are aware and involved.

"I can't and gave you notice" and "I just don't feel like it so no call no show" are very, very different things.  Coming in your room is an overstep IMO but having lived the wrestling life I could see my coaches showing up at my house if I were a junior/senior and the morning of an event I just straight up just wasn't there.

I probably could have been more communicative, though he did know I was injured, I think I had my mom relay the info to him that I was not coming because honestly letting him know I wasn't showing was giving anxiety.
