I also was scammed when I paid for an iphone with yicheng-f.us.
Do not use Western Union because they will not hold any money.
I was told that my money would be on hold till I received my phone.
I waited for my phone, then contacted yicheng-f.us, and was told they wanted more money, because the boss told them I had to purchase more product up to $500.
I was not able to get my money back, and the yicheng-f.us contact, kept on asking for more or I would not get my phone.
THEY ARE SCAMMERS OF THE WORST KIND !!!!
STAY AWAY FROM THEM. THEY ARE THIEVES AND LIARS !!!!
