Deliverer rang the doorbell briefly, after about 15 seconds I answered the intercom, but no one answered.
After a few minutes, I went down to look and found the package by the front door. It was simply parked there without letting me know. Simply irresponsible! It was about an article worth a few hundred euros and then placing the package next to the front door without a word is not acceptable !!!
