I have a clan mate in costa rice, he is finding it impossible to pay for his membership. He stuck on that axeso5 page, it will not let us send him runescape cards from the untied states, hes not able to pay w his credit card and doesn't get the whole axeso system> please fix this, its very annoying!! I love this game, but am very frustrated for him!!!
