I was looking to buy original mobile phones and psp consoles at Alibaba. I found this supplier asked his quotation. We were using only Alibaba Trade manager. I asked about his company credibility. He gave me his company's certificate of incorporation. He also gave me their recent shipment tracking numbers as 8692 4743 5953, 8704 4186 6325, 8704 4186 6347 (fedex.com). Then, he sent me proforma invoice confirming their acceptance of my order and asked me to send payment via western union. I insisted to use Alipay escrow service but refused and said as this order is very small amount, he cannot even accept payment via bank transfer. So I sent the payment of GBP 252.00. He took away my payment. Now he says, his boss doesn't approve my shipment as I have to meet minimum of 10 quantities. He never told about this before. Once he got my payment now he is asking me to meet their 10 qty minimum order. He is insisting to send remaining money then only he can ship my order. I told him that I don’t want their product and asked him to refund my money. But he is again and again insisting me to meet their 10 qty minimum order and send balance amount via western union again. He said he cannot refund my money. I told him that I would complain this about relevant authority if he refuses to send my money back. But he says he can neither send refund nor send my products. I have all his email correspondence, proof of payment, his proforma invoice and his company’s certificate of incorporation.
