They drivers the laziest worker on earth I guess. If no buzzer code they will not attempt to deliver ur parcel. Today, I scheduled for pick up and our building security called me that UPS driver is coming to my suite. I went out to my door with my parcel and left my phone in my bedroom . I waited for few minutes then I decided to get in to my bedroom to call security. I saw a missed call number and called security and he said driver left. Security said that driver left coz he called me and I didn’t answer my phone. He not supposedly call me, he should go to my door to get mu parcel.
