The only problem is that i don't live alone, we are a condominium so there'are more appartments, so i should set the next orders that they can put the package in the stairs.

You can perform the SE by using any of the two alternatives I've stated In my previous post.

And another question, after the package arrived, i should wait the notifaction that the package has been complated delivered? Then i will contact them?

As far as you're concerned, you're still waiting for the package to arrive, so contact them the next day.
