Franco Torvald [email protected]

Hello everyone, I was deceived by the supposed Franco, what happened was the following, contacted me saying that we could rent the apartment he had in Martim Moniz through Airbnb, then I made the payment of income of 6 months. It was agreed between me and Franco that Airbnb would send me an email, to tell me a place to pick up the keys and the rental contract on the day before August 20 so that on the 20th day, the apartment.
I come here to ask for help, because I would like to know how I can cancel the booking on Airbnb and how I can report the Franc.
I have all the proof of payment as well as print screens of the booking on Airbnb.
Please help me....
