Problems with Cities Skylines pre-order.

[Kie413]

If I or anyone else has pre-ordered the game before they added the deluxe addition, is it possible to get a refund in order to purchase the deluxe addition?

Also on the Paradox Interactive support page, there is no option for Cities Skylines.

I want to know the same have not located a option to cancel or to replace the preorder.
