Classic "1 star review because UPS lost my delivery" metric.
I'd guess most people have had a situation where there's a corporate problem, the support person you talk to literally doesn't have the tools or the agency to fix it, but then you're asked to rate their performance on whether or not they solved the issue, with no option to say "Actually they did their best but this isn't their fault."
> with no option to say "Actually they did their best but this isn't their fault."
In this case, the lack of such an option is obviously a flaw in the assessment system.
How to fix that? Major political issue, I suppose.
