1. As for you dispute with seller if it's Ali Express then the dispute will escalate or you have to make your dispute escalate.
2. For parcel RF477274925CN, this is the last 2 tracking:
2016-12-22 08:26:18.0 Guangzhou Transit Station export security scan
2016-12-22 10:57:02.0 Guangzhou Transit Station export customs scan (domestic transit )
3. The last tracking worry me, because it could mean 2 things either it's going to a new place in China for departure or going back to the seller because it did not pass the Security or Customs check.
4. You should contact seller and ask him what is going on with your parcel. If no response from seller then open a dispute.
