Phishing text?

I received the following text saying I’d purchased an app that I hadn’t. When I called to find out what was going on, they wanted info about my phone. When I told them I would not give them that info, asking if they could look up the purchase via the order number, the person told me to “just hang up the phone.” Should I be worried about this? The people that answered the phone clearly identified themselves as Apple Support. It then ended the call when I asked for more info.

Here’s the text:
