Worst part is, likely no compensation as it isn't the airlines "fault".

What do you hope to accomplish with the phone call?

Failures happen, does it make a difference if there's someone in charge feeling a strong emotion about it? Do the call center staff have to feel genuine guilt as if their mediocre job somehow made them personally responsible?

Being angry is just as useless as faking being sorry, all they're doing is acknowledging a screwup in an automated message. Give them a break.
