well, this is what going to happened
first of all, you will try to sell your D3, most likely without luck, because many con-artist selling 1450 USD (+delivery) device for 800 on eBay and many morons believe it, but that affects real owners and to sell D3 right now almost impossible without huge lost
next, you will start looking for better pool, better firmware, some tweeks and continue mining no matter what
later, DASH prices will go up and eventually you will get your money back and your miner will be still working and making some cash
everybody wants to have 3 months ROI, everybody understand now it will be 6-9 months at least
you can get f...d completely if iBeLink released 100 GH/s version for low price or you can won if DASH prices will go up

trying to return money from Chinese company is very bad idea
