Hello,
We are unfortunately unable to assist in any way with refund requests in cases where the purchase is not made from us directly. It is up to other companies to decide their own refund policies and whether a particular transaction meets the refund policies that they offer.
As previously stated in your other thread, Last Epoch has always been advertised on Steam as requiring a Last Epoch account to play. It is ultimately up to Valve to decide whether they are prepared to offer a refund request which is based on the game functioning as advertised.
At release, Last Epoch will have support for both offline-only, locally stored characters and online-only characters stored server-side and played in a server-authorative environment. Both of these character types will require will a Last Epoch account to play.
I am locking this thread as the core issue has been discussed at length, there is nothing more to add to the discussion, and we simply do not have any means with which to assist in this case.
