already activated iPhone 5 iOS 7.0.2 asks for activation - Unable to activate. now what?

So, my phone has not been used in 14 days now, cus my charger stopped working wich it shouldnt, I guess?

Anyways, thats not the point. When I finally got a new charger in the mail, I plugged my phone and powered it on.

Now it asks for activation. Im like; okay, didnt i do this twice already?

anyway, I tried to activate, both with wifi, and mobile network.

No success.

I even tried activation through iTunes.

NO ******* SUCCESS.

How come my device suddenly not work, while being untouched, out of power and completely unable to turn it on?

Someone help me out, I really want to be able to use my phone, and this situation costs me alot of money, while im unable to answere my phone.
