How to cancel Mobi Box by mail
Collect the details you need
Start with the email on the account, the plan name and the billing date shown on your latest statement, so the request to Mobi Box names the right account the first time.
Write the cancellation request
Because Mobi Box is dealt with in German, the letter is written in German (template de). Subject: “Betreff: Kündigungsanfrage – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Post the letter
Take the letter to the post office and ask for certified delivery to 10178 Berlin. Keep the tracking number it gives you.
Save the tracking record
Delivery confirmation is your evidence that Mobi Box was asked. Watch the next statement or two for any further Mobi Box charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a subscription box
Subscription boxes bill on a fixed day and ship later, so a request has to arrive before the next billing date and say that the plan, not just the next box, should end.
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.
