2. You should contact seller and provide him with the above tracking and tell him that the parcel is not departing China. The parcel has a problem, ask him to call China Post Hot Line: 11185, to find out what is wrong with your parcel.

3. Your parcel was rejected 2 times, look at the tracking closely.

Hope this help
