I got scammed by using Fx corp trading App.

They text me on social media and made friendship with me and talk like a normal friend and told me about his family etc to make trust and asked about me and my job and savings etc and then he said I'm so poor and he showed me some screenshots and said I've invested in Gold market (XAUUSD.G) and my uncle has more than 25 years experience in this market. He showed me more than 10,000 $ profit on every trade and said this opportunity is also for you. Then i said okay i will try with some amount just for check. I deposited 500€ and made profit 50$. He said more money make more profit and like so i added more and more money approximately 10,000 $ in just one and half month and i got profit more than 70,000$. And when i wantet to withdraw some amount they said i must pay tax extra and i must deposit 5000$. I was in shock. Actually in initially i tried to do withdraw some money and it was working that's why i was satisfied. And infect they was trying to take my trust on them. And so that they scammed me. This application still in my phone. They are still asking to pay tax on whatsApp. I reported to police but i don't know if they can help me. So please aware from this gang. No one calp you in trading.
