Prior to placing order with this supplier they were very pleasant. Promised a lead time of 7 to 12 days after deposit. As soon as the deposit was paid, 7 days later the salesperson sent a message saying he was going in long business trip to europe and blocked us on wechat. We then contacted the manager of this company who in turn started becoming abusive. We then requested a refund on alibaba trade assurance. The price they had quoted was far less than the market ruling price and this was a call for concern. After 2 weeks of arbitration alibaba ruled in the favor of the seller and denied us the refund. The supploer loaded a fake waybill to indicate the goods have been shipped. No packing list, No commercial invoice, no container no, no seal no, no evidence of goods. Trade assurance did not protect the buyer and the seller got away with fraud. We lost 7000 USD thinking if we use trade assurance we would be protected. We also noted that this supplier has been blacklisted before. However we only noted this after paying the deposit. This supplier was very pushy and constantly sent messages to pay the deposit. Whatever they promise prior to confirming the order they do not honour. This company is using the unfair terms on trade assurance contract to get away with fraud.
