You have contacted them by leaving a message here.  

I don't know about other devices, but on Plarium for the computer, there is a link to contact, right next to the link to the forum.

I believe there are other links too.

I need to contact support because about 7-8 hours ago I had an 8hour shield up and I put another 24 hours on just in case. I get up 7 hours later and I lost millions of rss and over 352k in troops, because lack of ease in contacting support makes me not even want to play this game and file a complaint against them
