Zhengzhou Great Machinery Equipment Co., Ltd review: Purchasing a fully automatic face mask machine

In early May of 2020 I negotiated a purchase for a semi automatic face mask machine and sent them some money as a deposit. About a week later I decided that I wanted to purchase the fully automatic machine and sent them money to cover the additional cost of the fully automatic face mask machine. In early June the machine was ready. I contracted with a shipping co. The machine was sold to me with the terms FOB. The first issue was they refused to bring it to the dock so just to keep things rolling and not get all hung up on this issue I agreed to pick the machine up. Then they refused to prepare the machine for shipping. Multiple attempts were made to pick up the machine but the seller always had an excuse for why the machine could not be picked up. So after about three weeks of that I hired a different shipper but they did the same thing to them as they did with the first shipper. In fact the new shipper actually went to the warehouse twice to pick the machine up and they refused to release it. We tried one more time on July 28 2020 to pick up the machine and it was made very clear by the vendor that they will not release the machine and for them to stop trying. this company Zhengzhou Great Machinery Equipment co., Ltd took my $42, 000 usd with no intention of giving me my machine. Basically I was scammed by them.
