How to cancel Onda by mail
Find your account details
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Onda holds, so the request can be matched to your account.
Prepare the letter
Postbye drafts the request in Italian, the language of Italy, with “Oggetto: Richiesta di cancellazione – [your name]” as the subject line. It asks Onda to close the subscription, stop billing and confirm in writing.
Mail the letter with a receipt
Send the letter to the Roma mailing address shown below by certified mail. Keep the tracking number safe.
Keep the proof of delivery
File the receipt with the letter. A Onda charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Onda cancellation letter goes

Before you cancel Onda, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
