How to cancel Fastweb by mail
Gather your account details
Check the account number, the phone number or service address being cancelled and the name on the account before anything else. A request that does not match the account on file at Fastweb is the easiest one to set aside.
Prepare the letter
The request is prepared in Italian (template it), under the subject line “Oggetto: Richiesta di cancellazione – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Post it with proof of delivery
Take the letter to the post office and ask for certified delivery to 20139 Milano. Keep the tracking number it gives you.
Hold on to the receipt
The receipt dates your request. Look at your next statement for any Fastweb charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Fastweb cancellation letter goes
For a letter to Fastweb, use Piazza Adriano Olivetti 1, 20139 Milano, Italy.
Copy the postal code 20139 exactly: it is what routes the letter to Lombardia, Italy.
Your name, address and email appear in a short block labelled Titolare dell'account, Indirizzo di fatturazione registrato and Email registrata, under the greeting “A chi di competenza,”.

Cancelling a phone or internet plan
Phone and internet providers tie cancellation to contracts, equipment balances and notice periods, so the request should name the exact line or service and ask for a final bill in writing.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
