How to cancel Bismart by mail
Find your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Bismart is the easiest one to set aside.
Prepare the letter
The request is prepared in Portuguese (template pt), under the subject line “Assunto: Solicitação de Cancelamento – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Post the letter
Take the letter to the post office and ask for certified delivery to 1170-014 Lisboa. Keep the tracking number it gives you.
Save the tracking record
It shows the date Bismart received your letter. Check your next statement: no Bismart charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Bismart, 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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
