ibuygou and mi3 wcdma

hello all

i have ordered the mi3 wcdma version 4 months ago and haven't receive it yet.
i tried to contact them to get my money back , but no answer by mail, skype etc.
did anyone ordered from them 16gb or 64gb and got it ?
it is safe to order from theme ?
what about shipment time, how much time it take ?

thanks
