Sorry about that! We recommend contacting your bank first and ask them why your payment got declined. A blocked charge is the most common reason for payment issues, so contacting your bank may help clarify the issue. Especially if you make a purchase from another country.
If your bank can confirm they're not blocking the charge, get in touch with us so we can take a look at what happened.
Please also check your payment details and make sure those are correct and up to date.
