Tracking shows "returned to sender", what should I do?

There are 2 common reasons that make your package be returned: Your shipping address is incorrect/insufficient or you are absence at the time the packet was attempted to deliver.
In cases where your shipping address is not correct, we are not able to take any responsibility since we shipped it out to the address that you provided us and it is not the mistake from our end.
Otherwise, we are willing to send you a replacement. If the second package cannot reach you, we are sorry to tell you that we are not able to help you out with this.
