2. Maybe they should have told you working days excluding the time spent at the Customs Office of both countries.

3. Now it's up to USPS to scan your parcel on arrival in USA or when they have time to do it.

4. Lately parcel to USA are very unpredictable, delivery can range from 13 days to 35 days calendar days for E Packet and even China Post Express Post Service (EMS).

Hope this help.
