PACKAGE# RG740573641CN ALREADY DEPARTED TO FINAL DESTINATION

HOWEVER PACKAGE# RY780422358CN STILL AT EXPORT SCAN BUT THEY WERE PURCHASED AT THE SAME TIME AND FROM THE SAME WEBSITE THEY SHOULD HAVE BEEN IN ONE PACKAGE I DUNNO IF THE SHOP HAD FORGOTTEN ABOUT IT AT FIRST

PLEASE NEED AN UPDATE WHY ONLY ONE PACKAGE WAS SENT AND THE OTHER IS STILL AT CHINA POST

You need to calm down. Postal shipping doesn't work like a courier. It's often many weeks between tracking updates and packages can take months to arrive. Two parcels sent at the same time can take different paths to their destinations and even arrive many days apart. All of this is normal and does not mean there is anything wrong with your shipment.

Both of your packages have left China for Lebanon:

Now there will probably be a long period of time with no updates, for both parcels. While the parcel is in transit between China and Lebanon, its status can't be updated, it's in a sealed mailbag and nobody can scan it. When the parcels arrive in Lebanon and are scanned by Liban Post, the next status update should appear. This could take 45 days or more.
