I would echo other responses to your query. Unfortunately, If your seller is not a registered seller on Alibaba, you are scammed. Alibaba will not be on any help, they will start making excuses and wasting your time that you submit complaint to our so called security or protection team. after few days they will say Sorry, seller is not registered member so we can't track him. They will also say, we've blocked the seller,however, you can search similar product and seller on Alibaba, and that thug will be cheating with other name.
This could be you training fee to stay away from scammers and alibaba.
best of puck.
