Well, in May I received word from Trenitalia that a major part of our June 2020 itinerary (Naples - Florence - Siena; Bologna - Rome- Fiumicino) had been cancelled, with instructions on how to apply for a refund. In June, I received an email saying my refund had been okayed. In October I received a partial refund, with a notice that the remainder would come immediately.
And finally, December 22, I got the rest of it applied to my credit card. Whoop!
