If you have a subscription with Apple or Google, you have to change the payment method in the respective service.
If you have a subscription from Billdu (you get an invoice directly from us), follow this procedure:
Log in to the Billdu website
Navigate to Settings - Subscription
Click on the red STOP button
The subscription renewal stops but your subscription continues until it ends
When your subscription expires, buy a new one and use a new payment method
