Don't sweat it, because it might aswell have been me at some point, since I am not sure whether I still have those other people in my friendlist.
Either way, they already replied back to me (customer support is really quick ) and mentioned I've answered everything correctly besides one thing, I had to name 4 cards I had on my account and mention their name, rarity, attribute and such, and I thought they ment name a card you have 4 copies of (which is 0, which I told them). I've already send a mail back and am waiting on a response.
