Wrong CC information
Payments can fail when your credit card info is incorrect (missing CVV, incorrect ZIP code, wrong number, expired card). So check if all of these are correct. If a payment used to work but suddenly does not, it is likely due to an expired card or insufficient funds in your account.
If your credit card expired here is how you update it:
Update payment information
Bank declines charge
When your first payment fails it is often because your bank declines the charge.
We are a Swiss Company and some banks decline payments by default that go to another country.
In this case you need to call your bank and let them know you want to make the purchase so they can let it through.
You can email us to firstname.lastname@example.org to inquire why a payment failed.
