I am old, work in a large corporation and don't know a single person who does not text. I am involved in many groups including competitive sports and in every one it is required that everyone texts as that is the only way information is sent.
It is rare that someone does not text these days. I don't think you can even find very many cell plans anymore that do not include unlimited texting. I would have taken the chance and sent a text to his phone. 99.999% of the time, it is a far more efficient way to contact someone than waiting for hours and continuously calling with the hope of someone answering. Texts can be glanced at anywhere.
If you are saying the OP doesn't text, he probably ought to learn. It is today's method of communication. It would save him a ton of stress.
