I think I got scammed because I actually bought iPhone with them. There is no way I can contact them.

I got this on message page

Due to too large message volume only our customers who have already bought from us will be able to use this message function.

If you want to talk to us, please make an order first. We always reply to people who made a purchase within 12-24 hours!


Is there any chance that I can got coins back? Can somebody help me out?

You got scammed.  How does it feel? I never got in such situation but I bet it should feel pretty stupid.
