Rhenus logistics cant deliver anything on time

To get a parcel to your warehouse seems to be very fast. To get the parcel to the clients seems to be taking very very very long even when you say it is loaded for delivery. What does loaded for delivery mean?? It says now for 3 days on delivery. this is the worse logistics serves i have to deal with to date. I just hope you don't need to deliver medical stuff. Then you will have blood on your hands. Please people STAY VERY VERY VERY VAR AWEY FROM THEM
