How to cancel Sinergas by mail
Note your account details
Have the name and email on the account and, if you have one, an account or customer number to hand. The details in the letter need to match what Sinergas has on file.
Set out the request
Postbye writes the letter in Italian from our Italian template, because Sinergas's address is in Italy. It opens with the subject line “Oggetto: Richiesta di cancellazione – [your name]” and asks Sinergas to end the subscription, stop all further charges and confirm in writing.

Save the tracking record
The receipt dates your request. Look at your next statement for any Sinergas charge after that date.

Before you cancel Sinergas, 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.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
