I think it was good for you to speak up and say that about seriously calling 4 times in a row. Granted she hung up and used the word attitude. I wouldn't take too much stalk in her using that word as it was probably a momentary word projection. The hanging up to me symbolizes the notion that it's you who "hangs up" by not tolerating such moments if that makes sense? It was your boundary. As in don't call me 4 times in a row. Without directly expressing it.

I agree sounds like she's having a bad day. When it's calm perhaps ask what's really bothering her-not the lost wallet, not the keys. That is, if you choose to and want to.
