Dear K. Kusuma,
We have sent email to Ostern for you already, we suggest that it is better if you send it to them again because you are their customer and they listen more to you. Thank you.
Also you need to inform your customs broker to look around the container whether the container is damaged or not before it leaves the port. Understood that you used to work with shipping company so you may know some procedure about this. I will talk to you again tomorrow.
