Not delivering package

Aramex is by far the worst courier service I've ever had to deal with. Apparently sending something by "courier" takes more than a week and is stuck at the same "sorting facility" for five days. They don't bother answering customer service messages. Now the building where I wanted it to be delivered is closing today for the holidays, so they'll be arriving at a closed building and I will be out of town. I can't change the delivery address or even pick it up where it is, because they don't answer my message in which I'm requesting this.) If by any chance an Aramex employee reads this, the tracking number is DBP***.
