How to cancel Gams by mail
Get your account details together
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 Gams has on file.
Put the request in writing
The request is prepared in French (template fr), under the subject line “Objet : Demande d'annulation – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Send the letter by certified mail
Send it certified to Molenbeek-Saint-Jean, Belgium, copying the address from the next section letter for letter, and keep the receipt slip.
Keep proof the letter arrived
Once the letter is delivered, the date on the receipt is the date Gams was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Gams cancellation letter goes
For a letter to Gams, use Rue Gabrielle Petit 6, 1080 Molenbeek-Saint-Jean, Belgium.
The envelope is going to Molenbeek-Saint-Jean in Bruxelles, Belgium, so the postcode 1080 must be on the front.
The letter greets the reader with “À qui de droit,”; your own details sit under the labels Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Before you cancel Gams, check these
- 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.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
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
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
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.
