About this matter, I have a lot to say and at least have some ideas on how to complain with courier companies!!!
I organized the 8th wine salon in chile, an international event and I had trouble with the wines from several countries to arrive on time, and then, ridicolous expensive to send wines.
Usually the courier companies are used to send wines overseas of Chile, but not usual to get wines from overseas to Chile. They overcharge so much besides, they never inform to the sender about their wines when they arrive.
Courier companies are killing the business of sending samples I think, and affects the entire market chain when you talk to an importer or distributor..etc...
