We met online, from friends to lovers. His name is Chen Jianguo. He is said to be from Chengdu, Sichuan, China, and living in Singapore. He introduced his friend, Mr. He, an investment broker, to me and asked me to invest in gold and foreign exchange. On April 7th and 8th, I remitted 900,000, 600,000 yen, a total of 10,000 US dollars, to the Japanese personal account designated by Mr. He. Around 4:30 in the morning on May 6th, Chen Jianguo lost contact. Mr. He also lost contact. I applied for withdrawal of 7,000 US dollarson May 7th. It has not been processed yet. Unable to solve it.
