They don't care about your package

I shipped through Aramex Global shopper. It left Hong-Kong on 5 Feb 2018. Ten days later, 15 Feb, the tracking page still didn't show it entering SA. I contacted ********** and got no response. Then I contacted someone else and got told since my address was a PO Box address they couldn't deliver it. They didn't even try to contact me, and my parcel has been lying here for a week. They asked for my physical address and passed my parcel on to Clearance. It is now 6 days later and my package is still in Clearance! How can Clearance take 6 days, if they have all my detail, my ID number, my Invoice?

Really bad and sad experience.
