We do offer Amazon if you would like to purchase Artix Points for a Varium package in EpicDuel. You have to go directly to Amazon's site and look up 'EpicDuel' to find the available Varium packages. Then follow the directions on Amazon's site. Once you have made your purchase and receive the Artix Points, please then spend the Artix Points for the Varium package you want. Here is our help page for more information how to spend Artix Points.
We cannot assist customers with most Amazon payment issues as we don't have access to their system, so you most likely will have to contact Amazon via the Amazon Games & Software Downloads Help Section. They also have a FAQ (Frequently Asked Questions) which includes a link to their Customer Service. Please keep in mind that all sales are final according to the Amazon Games and Software Terms of Use.
