2. It means that the parcel was refused by the Airline security check. There is a good possibility that the parcel will be return to the seller.

3. May I suggest you contact your seller, provide him with the full tracking above and tell him the parcel was refuse/rejected. Both of you will have to come to an arrangement.

Hope this help.
