How to cancel Vietnam by mail
Collect the details you need
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Vietnam can only act on a request it can match to an account.
Put the request in writing
Postbye drafts the request in French, the language of France, with “Objet : Demande d'annulation – [your name]” as the subject line. It asks Vietnam to close the subscription, stop billing and confirm in writing.
Mail the letter with a receipt
Take the letter to the post office and ask for certified delivery to 59718 Lille. Keep the tracking number it gives you.
Save the tracking record
The receipt dates your request. Look at your next statement for any Vietnam charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Vietnam cancellation letter goes
Vietnam takes its post at CS 90006, 59718 Lille, France, which is where a cancellation letter belongs.
Copy the postal code 59718 exactly: it is what routes the letter to Hauts-de-France, France.
Inside, the salutation reads “À qui de droit,”, followed by your details under Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Before you cancel Vietnam, 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.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
