I think you're making a big deal outta nothing.
They turn around in my driveway too, and I've never gave it a second thought.
Don't call the company; it could cost a person his/her job.
If it bothers you that much, then politely speak to the driver about it.
Perhaps -- since we are all living in these very uncertain & unpredictable times -- you could put your energy into finding things to be grateful for each day, show kindness toward people you don't know, and appreciate the men & women who drive the trucks that contain the goods you need to live a comfortable life.
