Would you pissed about this or am I overreacting?

I reached out to my uncle to ask if he wanted to come to a house inspection with me a week ago, but I told him repeatedly that if he got called in to work to please let me know so I didn't waste my time driving to pick him up. Well right as I am on my way to pick him up, I call him to let him know I was 10 minutes away from picking him up and he tells me he is at work.

He does not have set days or times for his job. Sometimes he will be told the day off he is working, but he always get told by 10am if he is working. It doesn't bother me that he is working, but it's the fact he told me repeatedly that he would tell me if he was working or not so I didn't waste my time driving his way and he didn't bother contacting me to let me know he got called into work.
