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?
if you already made an order and paid for it, i think you can make a message to them regarding your order ( as you said)
