Stuck in Tuscany without any options

Hello my wonderful travel friends.

Long story short I am travelling to Italy. I badly planned the trip, and ended up in Chiusi and took a taxi to Contignano for a nice hut I rented.

But what I learned is that Tuscany is a very car rental-oriented place, and I have not ordered or looked at public transport. Even the taxi was a mistake .

In this small beautiful village there is not much public transportation. Uber doesn’t work and google isn’t helpful.

How do you get around, or how would we even get back to the train station in Chiusi? There is probably some official cab-app?

Any tips would be greatly appreciated. Got myself into quite the pickle. :) I would walk but it is 48km
