We bought 8,000pcs USBs from Shenzhen Zhongwei Technology Shared Limited last June 20, 2016. They showed their Alibaba credentials and other information to appear legit. Unfortunately, 99% of the USBs are defective upon receipt on June 22, 2016. Company representative and owners refuse to neither talk to us nor fix the issue!
I had received a mail from Mr Alvin Lin, regarding product prices. I thought he was genuine as i had posted a product quotation on alibaba.com recently, and I thought that he had seen it and replied me by mail. I asked him his Skype ID for further conversation and exchanged many messages with him regarding the procedure, the payment details and all related information regarding my order.
