Deceived by this broker

I opened an account with this broker and their agent came and contacted me promoting her signal service. First I deposit $200 and made nearly $300 profits with her signals. However, things started to be different since my second deposit. After getting my trust, the girl convinced me to make a deposit of $3,000 to earn more money. But after I applied for a withdrawal, my money wasnt withdrawn for a long time. I was told because of my change of withdrawal IP address, my account was temporarily under protection. I was told to make a deposit of $4,500 so that my account would automatically remove the protection system...of course I did it...BUT this turned out to be not enough. I wrote to the support service, and they said that I still had to make a deposit because the deposit the girl made seemed abnormal. I wrote to the girl, and she reacted negatively and said that I should return her money. It was then that I realized I had been deceived.
