A worker was supposed to come to look at my ac. I changed all my plans to wait for him. He didn't show up and didn't call! 
A worker was supposed to come to the house to fix my air conditioning. I changed my plans for him and just sat there. Then he never showed up and didn't even bother to call.

That's annoying, did you call him after he didn't turn up?
assistant
We didn't bother. At that point, we didn't want to use him anymore. 
user
That's understandable. What a frustrating experience for you.
