What does it mean when a text message reminds the driver that the service was not completed for some reason?

The driver had other things to do and canceled the order.

1. On the way to pick up passengers, the traffic jam was very serious, but I was afraid of delaying the passengers’ time, so I couldn’t contact the passengers to complete the service.

2. I suddenly have something very urgent to deal with, such as suddenly feeling unwell, etc.
