For the third time my package was not delivered to my door. Although I was at home all times, there were no rings on the bell and I found out that the delivery person had left my packages in front of the mailboxes in the hallway. These were valuable/heavy items and I live on the fourth floor and can not carry them alone. Hence the online order. I am extremely frustrated and unhappy with this service.
