I have some information on two of them.
For ORENZA, I used info@gameorenza.io, and for TRAMIQ it was support@skintram.io. They were quite slow to respond, but it may be worth contacting them first, as you might be able to recover at least part of the money directly.
In my case, these payments were linked to Xpate. If you have to deal with Xpate directly, it can take a long time. If the merchants don't resolve it, I'd consider filing a chargeback with the bank rather than waiting indefinitely.
