Can't withdraw fund. Later say government tax later say process fee.

At first, a girl said to help me solve the economic problem ask me to join this games. When I mention the withdraw, customer service told me need to pay Government tax 10% of USD 23K for Singapore. But given me SG personal account, why not I direct pay to Government? After they know I had asked the Government. They attitude has bad. Now told me is for processing fee. I will not pay any amount for this. Now I just want to get my money back USD7K.
