I went following path(not logged in with my account)- Main Web --> Click on "Cipsoft" (under TIBIA logo in Top left corner)---> click on "Contact".
When you logged in, it goes directly to their internal form where you can choose what you want to enquiry.
Normally Companies has simple and visible" Contact us" option with disclosed information's about company and possible ways of contacting- like phone number, emails or letterbox.
Imagine what would happen if there would a phone number............. I would feel sorry for anyone holding customer service role and speak with anyone calling there (I already feel sorry for Rejana, Mirande and Skerio when I see some of the posts on forums).
