what's the status of my pacckage (tracking number: RB708901415CN) right now?? Will it be delivered?

2 months ago I did some business witth an online shoe store and they referred me to this postal service in order to know the status of my packge whose tracking number is RB708901415CN . I recently checked and it says like it was sent back to China !!!
I bought this item online from USA and its destination was the city of Caracas in Venezuela. What can I do? Is there a solution to this problem? Will I get it some day?? Can you help me with this, please?
