Coppermed

I ordered a pair of compression socks with three free on February 20, 2020 and have not received them. When I try to contact them I leave a message but no reply. I found out that the socks are coming from China which was not made known in the ad on Facebook. I want to cancel the order before I get them because it will be too hot to wear them by the time they get here. I also wonder if this is a scam. the ad said that their is a money back guarantee if not satisfied.
