Everybody be aware of HK Diao LTD, Juntong Zhong, Sara Huang, Aihua Yan, Changhe Xia they are all fraud. They took USD 500 from me and gave me EMS number which was wrong and could not be tracked. I waited 1 month then reported to alibaba, gold supplier (they r crap), Honk kong police, CCERT, Anti-Spam Center, and OFTA of Honk Kong to take action against these scamers.
