I need help, I use UPHOLD wallet and I wanted to buy an antminer s9 in the page of www.bitmain.com they told me a bitcoin cash wallet and when to pay and send the money to that bitcoin cash address, by mistake send bitcoin for 1450 dollars, and they could not confirm the payment. And now I do not know what to do?. where is my money. uphold gave me a blockchain confirmation address and the transfer appears but as (not spent) but neither bitmain.com nor uphold has given me a reply. I did this on Friday, November 17 and today, Monday, November 20, I have not received a response. What should I do? they can help me, they are 1450 dollars and I do not want to lose them.
