You can read more about declines in Stripe's documentation.
If you are faced with this problem, we recommend using a card issued by another bank or an alternative payment method available at the checkout page.
If it is not possible, we can prepare an invoice for you and ask you to make payment via wire transfer (bank payment). Once we receive the payment, we will create a user account on NorrNext site and manually assign a subscription to the product for you. Please contact us for further details.
We do the best our products to come with an extensive documentation, step-by-step tutorials and video guides. There is a large FAQ that have been updating to let a user get started quickly and solve potential question. More information can be found on Support page.
Commercial products get guaranteed support according to our support policy (see Response Time) and we are focused on providing the best service.
Free extensions come as is and no support is guaranteed. However, we do the best to provide critical fixes in priority order (with no obligation or deadline). In other cases, you can submit questions via Github issues in a section called Tracker. You can find the link on product page (Support button).
