Thank you very much for your reply (this is AngryPigeon speaking from another account), indeed I was monthly subscribed.
But I have no idea how to access the page you linked without knowing the link by heart. Seriously, how was I supposed to know that ? I keep searching on the gamerfirst portal, I really have no way to access this page. Or am I dumb ?
I'm asking because I'm might try to dispute the previously months I paid without knowing I was subscribed. If the page you linked is not accessible through their official portal, I find it a bit malicious to automatically subscribe people like that.
Thanks again.
