Am I in the wrong for being livid that my wife, my emergency contact, had her phone off when the hospital tried to call her about me?

Here are the details, about a month ago I was in a car accident. The hospital I was at needed approval for things, but I was unable to give consent, I was unconscious.. They called my wife repeatedly and could not get her. Eventually she turned her phone off. They were able to wake me up enough to get said consent, but if they were unable to do that, I would have died.

I was and still am very pissed off at my wife over that. Her excuse was ' I was trying to sleep and I thought it was a scammer' I told her if it ever happened again I would divorce her.
