How to cancel Streamz by mail
Get your account details together
Streamz will look your account up from what the letter says, so check the email address on the account, the plan name and, if you can find it, the billing partner shown on your latest statement first.
Write the cancellation request
Streamz is based in Belgium, so the letter goes out in French, built from our French template. Subject line: “Objet : Demande d'annulation – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Post it with proof of delivery
Address the envelope to Streamz, Vilvoorde, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
File the delivery record
File the receipt with the letter. A Streamz 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 Streamz cancellation letter goes
Streamz takes its post at Medialaan 1, 1800 Vilvoorde, Belgium, which is where a cancellation letter belongs.
The envelope is going to Vilvoorde in Vlaams-Brabant, Belgium, so the postcode 1800 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,”.

Before you cancel Streamz, check these
- Check the billing date on your statement and send the request well before it, so the cancellation lands inside the current period.
- If an app store, phone carrier or TV provider bills you, the service itself cannot cancel it. Cancel with the billing partner as well.
- Access normally runs to the end of the period you paid for, so a cancellation does not shorten what you already bought.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a streaming or entertainment subscription
Streaming plans renew silently each month, and many are billed by a partner such as an app store or a TV provider rather than the service itself, so the request has to reach whoever actually bills you.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
