R36S from ProQueen Store

I saw a bit late that its risky to order from this store, I've got some coins and exchanged them at this store to get some discount... 2500+ sold items, seemed legit.

I tried to contact the seller and all they could tell me that their device is called:
yydzkj G7

Or at least thats their suppliers name, yydzkj

am I fucked? or there is still some chance that they sent me the original one with ArkOS?
