I think it is best to contact chess.com support rather than posting in the forums. Also, I believe kohai is not staff anymore (even though the staff icon is still there).
You can contact chess.com support by clicking the "Help and Support" at the bottom of the page. Then click "contact" at the top right. Or you could follow this link directly: https://support.chess.com/customer/portal/emails/new
Hi there,
As paying for a premium account with Paypal from Germany does still not work (see http://www.chess.com/forum/view/help-support/paypal-payment-does-not-work), I sent 99$ to order@chess.com yesterday manually in order to receive a one-year Diamond membership for me.
This has worked a few times in the past, but sometimes I had to ask the stuff to finally update my account. If I remember correctly, I contacted kohai in these situations, but he does not receive message from non-friends anymore, so I ask here.
tl;dr: Please update my account as fast as possible to Diamond, I have already payed for it. :)
Thanks and regards, Keba
