Troubles Purchasing Update Licenses Follow

Hi,

First, I've tried to purchase directly on www.jetbrains.com, but it rejected my license key. Then I've contacted sales@jetbrains.com and received a link to your website where to order. I've entered all my data and one day later received a pro-forma invoice with a very old address. Later, one week ago, I've contacted three (!) times invoice@jetbrains.com and sales@jetbrains.com but received just silence. Sorry, but selling this way will not increase the income for Jetbrains.

Best regards,
Thomas Singer
