I have ordered a changing unit commode (60 kg). When the delivery man rang the bell, I was immediately downstairs, but he was nowhere to be found! Just the 60 kg package left for an 8 month pregnant woman to carry (!). It was a matter of only 15 seconds, so my guess is that he purposefully left it there (far from the optimal entrance) and left without waiting for me to sign in order not to help to carry it. Really horrible experience.
