Complaint Review: shenzhen wanfa kuke technology co ltd

Im reporting the company of SHENZHEN WANFA KUKE TECHNOLOGY CO LTD,  the person i talk to is the name JANICE DIXON  aks HAILIN WEI. She sent me message to my email about the apple products and different electronic and telephones stuff. I do believe this in Alibaba .com that this site and all there supplier is legit and they can transact business. Beacause im a buyer in this site and i dont have problem with this. When the times i received message to different company about the free shipping and  discount beacuse of the dragon festival thats why they have promo. I ask about the deals. to all the deals i transact she make me a good deal and looks legit when she talks to me, I send money thru western union  around $500.00 for the samples of the products she is offering. after i gave the money to her , she ask me there company have another promo  buy 1 free 3 because for the second order, i i told her, not now i want to see the sample of the products, And the next day she send me message i have to send her another $483.00 for my custom tax because my items is detained. I have arguments with her and she told me if i will not give the amount nothing she cant do i will lost my money. I told her i report this matter to alibaba.com,  she told me if i report the police will put her in jail i have to understand the business in china. and she makes me feel guilty about it. When i try to browse there company i see this report that she makes scam to lots of people around the world. This must be stop now like me i dont trust the alibaba.com now and the way i make transaction to chinese business.
