Uppruna tekstur - Enskt - contrattazione su e-bay

Hello,
This is the first communication we have heard from the buyer. They never contacted us through ebay to let us know that there was a problem. The item was shipped on 3-29.
We have experienced lengthy delays with the customs department in Italy. Let us try to investigate what has happened. We have to way of contacting the customs department in Italy however.
Is there any way for the buyer to contact their post office to try to see if there is any message from the customs department in Italy?
Thanks
