Yoopuff review: Men's air force a-2 leather flight bomber jacket

I ordered a large men's black leather jacket advertised on Facebook as made in the USA. I received an acknowledgement January 11, 2021 and was told that I could track my order at a listed website. When I accessed the website, the characters were Chinese. I suspected that the coat was not made in the USA. I asked Yoopuff by Email on January 23, 2021 to void the purchase and issue a refund. I tried by reply to their Email and to the support Email listed on their website. I received no reply. Today, Feb. 13, 2021 the jacket arrived. What I received is a polyester womens jacket, made in China. I am very unhappy. There was no return address or instructions. The company, in the past, has not respond to Email contacts. The return address on the shipping label is PO Box 6368, Rosemead, CA 91770. I understand, they will not accept returns. How do I return the jacket for a refund?
