A colleague who had faced a similar issue sent me the link to the Entity on my Bio. I’m glad I listened. They helped me file the right disputes and gave me back some control.

A primeira vez que ouvi falar desta empresa foi através de um anúncio no Facebook. Pensei: "Porque não?" e ​​comecei aos poucos. Continuaram a incentivar-me a investir mais para "retornos maiores". Depois do meu depósito de 27.500 dólares, bloquearam-me. Fiquei muito zangado. Um colega que tinha enfrentado um problema semelhante enviou-me o link para a Entidade na minha Bio. Ainda bem que ouvi. Ajudaram-me a registar as disputas certas e devolveram-me algum controlo.
