How to cancel Speedster by mail
Get your account details together
Speedster will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Prepare the letter
Postbye drafts the request in French, the language of France, with “Objet : Demande d'annulation – [your name]” as the subject line. It asks Speedster to close the subscription, stop billing and confirm in writing.
Mail it with tracking
Address the envelope to Speedster, Abbeville-Saint-Lucien, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Save the tracking record
It shows the date Speedster received your letter. Check your next statement: no Speedster charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Speedster cancellation letter goes
Speedster can be reached by post at CS 60003, 60480 Abbeville-Saint-Lucien, France.
The envelope is going to Abbeville-Saint-Lucien in Hauts-de-France, France, so the postcode 60480 must be on the front.
Your name, address and email appear in a short block labelled Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré, under the greeting “À qui de droit,”.

Every address we hold for Speedster, with the envelope wording
Before you cancel Speedster, 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 mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
