Trandung Llc review: Purchase of two GMC Serra 2500 AT-4

Purchased through Alibaba, seller claim t be in good standing with a gold rating with Alibaba and that all conversations were monitored by Alibaba. Seller asked to be paid direct to his bank account sent bank transfer including delivery. Received a shipping notice from Safetakers logistics and an additional billing for $6950 Safetakers logistics seems to be a fake company with no traceable ULR. After contacting Jimmy Tran Dung he told me to pay the shipping fee and that it would be refunded by the shipper upon delivery. I asked to pay through Alibaba trade assurance and was just pay it direct, I asked for some kind of paper work and he refused saying it would be delivered with the trucks. I asked for a refund, not another word from Tran Dung LLC
