I used to buy VISA virtual cards on card444.com. Years ago they contact me if I wanted to invest in a program to earn interests beyond the money invested. I sent them US$ 3.000 via Western Union. On the first months when I asked about the interests earned so far and to reinvest, they replied.

About a year ago I asked them for the money back and they never replied again. Even if they kept the investment and gave me only my money back. Despite several emails sent, I never heard from them again.

I only have the emails exchanged in the beginning as proof. Could I also file a complain somewhere ?
Thanks.
