UPS and FED EX delivery drivers

The Amazon Prime drivers seem to be OK, but putting a package in front of the screen door you have to open seems a bit ridiculous.
I've had that happen too. I put a sign on the door asking them not to put packages in the step zone. Sometimes it works. No easy way to complain to amazon either.
I asked a Prime Driver if they ever see the delivery feedback and he chuckled and said 'no' so I stopped doing those.
