What are you hoping to achieve by pursuing this further?

You seem intent on asking rhetorical questions that can’t be answered in order to demonstrate how aggrieved you are. If truth is what you seek, I suggest you fill out a job application to be a baggage handler for Delta. Do a rotation at every airport Delta operates at and then finish it off at Delta Corporate.

I sincerely hope that you’ve been sufficiently remedied for your hassles with the delayed and damaged bag. If not, chalk it up as an L and move on.
