Did I respond badly to his cancelled date?

I met a guy on an app and we were meant to go for our third date. However, two days before he cancelled saying that there was an emergency at work and could he let me know of any alternative day the following week? I replied rather curtly with 'Sounds difficult... Hope things get sorted out' as opposed to my usual lengthy replies, the reason for this was that he had been taking days to reply (again due to work) which annoyed me. Since then it's been 2 weeks and he hasn't got back in touch after my reply. Did I reply too coldly?
