One could be and I have been waiting on shipment from FEDEX and never know that they are even on the property. Very stealth like-never will they knock or ring doorbell to let you know of delivery. I asked last Fedex delivery why not, and he replied that he wasn't told to. What's up with that??? It is almost like their drivers are either in the witness protection program or child molesters and they don't want to leave their fingerprint. IF I HAD MY CHOICE>>>>>I would never use this carrier service for delivery. Very very unprofessional, I wonder if any upper management reads these reviews????
