I ordered gold detector devices that do not work worth 15,975 USD while I was in the country and they shipped it to me and now I have complaints from customers in my office in Burkina Faso. I brought all the machines back to their shop and the shop does not want to exchange the devices and does not want to refund me and it is the same with customers who have already taken the machines and found that it does not work, they do not want to exchange or refund me.
