No, no, no - let me tell you from my experience being her mother does not work and reflects badly on you.
You don't know why her phone was switched off. She could have been ill in bed with a migraine. This is called assuming and we all do it big time in the beginning, it makes an 'ass-of-you-and-me. Assume.
Will looking at her with utter contempt get you towards your main goal? This is a DBing opportunity - be a great father today. Be cool, you are getting on with your life now and it is great. Don't let her push your buttons. If you want to address the phone issue, do it in private later and people may have tips about how to approach it?
