First a little check:
- Have you properly filled in your credit card informations?
- Have you reach the maximum limit of your payments made online during a certain period of time?
If you cannot figure out why it is not working, contact us at email@example.com with the mention "Payment Issues" in the email object. Better, you can use the chat window in the bottom right corner of the screen to get in touch with us. We will get back to you quickly (if not instantly) ⚡️
