Nostale blocked my payments from steam because they need print evidences of my card.
I tested in Gameforce client after linking the account and same method works in their client with same account.
For the payment method i created a card in MBway in both situations.
Still confused why Gameforce support asked prints of my card from front and back, that i will not share, when same method worked using their client. They only blocked steam payments.
A lot other players complains of same problem in forum, but did not found anything related to the problem that should be the same.
They should have fixed this since it's related to payments and it's in their best interest.
Too bad i can't left the prints here.
