SCAM!!!

Someone forced me to deposit a huge amount in order to gain double. He even forced me to overdraft to platform and have to recharge the same amount to withdraw my money. I read some articles about this and they still not withdraw their money even they paid the overdraft. I told the customer service to get back their 10000usd but they refuse it, they want me to deposit 10000usd so i can withdraw the 15000usd. I don't know how to get back my 5000usd.
