It comes down to a price.

These big shipping companies started out good, but with time things slid downhill. You don't start out with the goal of providing mediocre service.

The problem is if you want top employees, you have to pay top dollar. Amazon's shipping service company will probably start out good, but it may windup in a similar place once they start trying to "optimize" their shipping service.

They will cut cost, overwork existing employees, and try to extend the reach of their service. If they don't, you will be over-paying for "Amazon" services and many will look elsewhere when it comes down to paying an extra 5% or more for better service.

On the topic of feedback: You can provide feedback to shipping companies. I called FedEx and reported their driver for dropping 2 packages in a row (and damaging the contents). He came back 2 days later with the 3rd package, apologized, and read me back my report. You just have to be proactive and communicate with them.
