Unable to withdraw and deny it by various reasons

My friends and I have opened several accounts on their platform to do transactions, and each account has about 20,000 to 30,000 US dollars! I have been making normal transactions and doing transactions, but I just don't give money! Every time I say something about Jin, I stop it for one reason or another! Recently, there is another saying that the customer service staff always try to prevent me from withdrawing money in the form of emails. Please pick up my post, help! It is not small money! It's life-saving money!
