You say you can't do anything... But it's that you are choosing not to do anything.Man that does suck I would definitely been at the p.o. we reship if seized but can't do anything if it shows delivered was it finished or raws?
You have good neighbors I would ask around.
It's not like if it's a customs seizure then you make a claim on your insurance... You just take the hit.
So whether you do something or you do not, it is your call - regardless of the circumstances.
I'm not even saying you should re ship it, but saying that you can't is bullshit... You won't, not can't.
We all want a good service at the end of the day. The postal service is not infallible in any country.
