I suggest you strongly learn and/or heed suggestions and customs laws of the country you are shipping to..
As example, Italy tends to be combined with Russia as a problematic country to ship to/from. I can state that shipping and postal service within Italy is just as good as the US, however people aremignorant as to the customs laws. Jewelry, watches, leather items, cannot be imported and may very well remain within la-la land indefinitely. This doesn't apply to EU countries.
Russia also has similar customs similarities which unfortunately Im not aware of.
If the post office employee told you so, LISTEN..
Laugh as you will, but customer service within the USA is the best in the world.
People easily blame others (especially regarding online transactions) but many problems are a result of ignorance.
Be careful and best wishes.
