How to cancel Karperwereld by mail
Get your account details together
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 Karperwereld is the easiest one to set aside.
Set out the request
The request is prepared in Dutch (template nl), under the subject line “Onderwerp: annuleringsverzoek – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Send the letter by certified mail
Use certified mail for the 2408 AN Alphen aan den Rijn address in the next section, so the post office records the delivery. Write down the tracking number.
Save the tracking record
It shows the date Karperwereld received your letter. Check your next statement: no Karperwereld charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
