That sucks Mick. At least call and say you're not going to be seen. VA did that to me last month, cancelled my appointment without telling me. I was pissed. But I had already showered and brushed my teeth for the visit. You even put on clean skivvies? Those bastards!
We live in a world staffed by incompetent people. During the ice storm last month the PT place calls and says they will be closed. I say no problem, put that scheduled session on the next open Monday after my last scheduled visit (today). I arrive promptly at the appointed time and guess what didn't happen. Now I have brushed my teeth, showered, changed underwear and put on clean clothes for absolutely no reason.
You could take this opportunity to go see the Proctologist........................or not
