Nice game BUT...!

I paid for almost all types of airplanes, but got tied of the game and deleted it.. Know after about a 1/2 year I downloaded it again, But it wants me to repay all those same airplanes, That I bought a 1/2 year ago.!
Normally if you bought something in the past? It lets you "Restore" your previous purchases!
But there isnt a "Restore" button anywhere!
So I tried to get the airplane from before (thinking it will restore that previous purchase)? Not it wants the $$. I contacted the company directly but havent heard from them? Lets see its been 1.5 weeks and counting..!
