I have had several parcels sent to me from Italy and all of them eventually reached me. They usually take longer than parcels from France or Germany, but their tracking is very detailed, up to Borromeo, Milano, which is where the parcels leave Italy.
Then, it is up to the receiving country postal system.
The strangest thing that has happened to me was a parcel that took almost three months to go from Sicily to my place. The first week the parcel made it to Madrid (Spain), where it disappeared for two weeks, to appear back at Milano, where it went missing for four weeks, reappeared at Madrid, apparently went back from Madrid to the sender, where it finally disappeared from the tracking system, and when I was going to ask for a refund, the postman rang at the door, and there it was the parcel, without the tracking system showing anything.
During the whole experience I talked several times with the Spanish post office, who could not explain the back and forth shipments from Madrid to Italy, and with the sender, who was not exactly happy about the whole situation, and was not very forthcoming about what he did (if something) to solve the problem.
That was how I learned not to obsess myself with the tracking thing. It is mostly useless, at least in Spain.
