Guild Wars 2

I got max Legendary Crafting mastery but can only buy the items from the first tab, the rest are still locked even though it shouldn’t be locked.

I’ve tried about 12 hours ago and a few hours ago, I got a message that the transaction failed, so I try using another credit card and it also fails. The card that I use is the card that I bought the game with so I don’t know what is the problem why I can not buy gem
