Hello, I purchase a watch on Aliexpress on November **, **** (Order ID ****************) but it stopped working in two weeks, so I contacted the seller to return the watch for a refund. The seller deliberately told me to ship the watch directly to him and did not tell me anything about going through the official Aliexpress return process. I shipped the watch back to the seller at my own expense and waited for over two months but nothing happened. The seller still insist that he has not received the item and would not give me any refund. I've uploaded all the evidence within the Aliexpress dispute channel and contacted the Aliexpress customer service several times during this period, one agent (named Francis) promised to refund me the full price after one month. I've disputed twice on Aliexpress and uploaded everything I have but still have been told my dispute was not successful. I've paid over $*** but now I've got nothing! This is unacceptable!
