Scammers do not allow to withdraw money

Hello! It all started when a girl from China wrote to me on Instagram in the spring of this year; she introduced herself as Liu Tingting; After several days of communication, she offered me to earn money using her signals on a trading platform called DeFi. Everything went well, I made a small profit, after which she told me to withdraw my money and move on to the next project that she created together with traders who gave signals to the Ark Community called BLaFX, claiming that this project would be more large-scale and profitable. I immediately invested there all the money that I had withdrawn from DeFi and at first everything went well, I copied traders’ transactions, made a profit, and could withdraw money. Throughout the entire time, the girl from China who invited me actively wrote to me that I should invite friends and relatives, telling them to take out loans because... it guarantees that we will not lose our money. Suddenly BLaFX announced a promotion of +100% to the deposit and throughout the entire promotion there will be a ban on the withdrawal of funds, before this promotion there were no announcements either by email or on the website that withdrawal of money would be prohibited, this is a gross violation 19.08 Liu Tintin persuades me to deposit $2000 to get a bonus. 08/22 I learned from support that it is prohibited to withdraw money while the promotion is ongoing. A couple of days after this, support said that there were suspicious actions on my account and that to withdraw funds I needed to deposit the amount of 15% of the total deposit, a little later an announcement appeared on the site that the site was ceasing its activities and to withdraw funds you need to deposit 27 %, On the website, support wrote that you need to contact their telegram @Blafx967 when communicating with support, they started insulting me and did not give any normal explanation about the suspicious actions from my account. Please help me get my money back.
