Shandong Mailan Import & Export Co Ltd review: fraud company - not contactable after receiving the advance payment

We got the information about this company from Alibaba.com. They have 2 websites "www.mailanchem.com" and "www.mailanmetal.com/". We contacted the company representative Wang Amy through email [protected]@mailnachem.com. We intended to buy Aluminium scrap 6063. After lots of negotiations, we received the invoice to pay a total amount of USD 15600. We paid the advance payment of USD 4680 in their bank account which is held with WeihaiCityCommercial Bank Co Ltd . However after receiving the payment, no contact could be established with this company or amy. We had also asked for their trade license, which they provided. As per the Trade license the owner's name is Liu ji kao. They are also not replying on the emails. The phone numbers are all not reachable.

This company is a total fraud and our advance payment has been lost. We urge everyone reading this not to trust these people.
