person A: 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. 
person B: That's annoying_comma_ did you call him after he didn't turn up?
person A: We didn't bother. At that point_comma_ we didn't want to use him anymore. 
person B: That's understandable. What a frustrating experience for you.
