Was I too harsh on the guy who stood me up?

I’ve been seeing this guy and it’s going well. He asked me to go on a date with him yesterday and he had me waiting all day. He called me at 10pm saying he’s gonna come soon and that he won’t be longer than a hour. 12am comes. I call him twice and no response. So I text him this morning saying ‘I don’t appreciate the way you kept me waiting, let’s not plan to meet again if you’re just gonna keep me waiting, I don’t have time for that’ is that too harsh? I’m usually a very timid person so I’m not sure if this was rude of me to say?
