Lost all my money and my account has been disabled!

I deposited a margin of $350,000 in my account. I was reassured because the broker claimed on its website that it was under the regulation of several authorities, including the Australian Securities and Investments Commission (ASIC). In the week following the deposit, I made a profit of over $20,000, a really high return. I submitted a withdrawal request for $100,000 on October 3, but it was kept under processing. Thereafter, I submitted another withdrawal request for $50,000, which was under the same status. These requests have not been approved yet. I contacted the platform's customer service at once but only received automatic replies. Soon after, I found my account disabled when I tried to log in again. I questioned the customer service but was still replied automatically. Until this time I realized I had been swindled!
