Calm down and try all possible solutions.

1) Contact carrier and see possibility of changing without Bitmain (unlikely).
Some carriers will attempt delivery several times, and then hold for pick-up at their office before returning package.

2) Contact Bitmain agents.
They have address change instructions in 2016 for China:

They also have Wechat chat representatives. Not sure if open to international clients.

Good luck.
