Seller sent the package with Cainiao. And I did not received, however Cainiao shows as delivered. Seller asked me to go to the post office when there is COVID pandemia and I paid for delivery To my home. However, I went to the most used postal service and they do not have this code tracked. Besides Cainiao and the seller did not know which was the local post office used. And there are at least 4 postal service in my city. And the seller only response is go to post office. I open a dispute and ask Aliexpress to investigate and still waiting response. Due seller do not want to refund me,
