Shady 7riches site (OLGA!!!!!!!!)

I saw on chime that This 7riches site Olga was advertising a100% match deposit when you sing up. So I singed up expecting the bonus when I deposit because on the opening page the bonus is listed Frist . So I deposit money and after I lost my money I ask there customer service where the bonus is and was told that if it is lost listed with the my accounts promos then it has expired. But I saw the adv today and when I went on the web site it state that to receive the bonus you have to sing up.
