I withdrew my ETH from UCH yesterday. Everything seems to be normal at first, they sent me an confirmation email with security code with my correct MEW address. Later on I checked History of transaction in their website, it showed "Completed" with txid. Go to my MEW wallet, still nothing. I checked back the txid and found the recipient address was a different address from mine!!!! Traced to this address, I saw all its balance was sent to a second address with total balance of 9 million USD. Seems everything well explained!!
I wrote email, send messages, creat support ticket and heard nothing from them!.
