Canceled the second half of a EK J round trip 30 hours before departure from ORD. I say canceled, but for whatever reason EK won't let you do that in the app or online. I believe the agent put it in 'deleted' status from what I recall. Said I needed to fill out a form online to get the meager refund they give for partially used tickets. Which is a terrible way to run things, but that's another point.

A few hours after I 'canceled' over the phone, the chauffeur company called me to verify my booking. I told them I wouldn't be traveling. 24 hours later the chauffeur driver calls me to tell me she's in my driveway. Was perplexed and annoyed by Emirates, and the chauffeur company, especially because it was the same wonderful driver I had last time, who was quite pleasant and friendly.
