The website has been closed unexpectedly

They are so bad. They dare to close the website. I asked the customer service how I can get my money back and I was told that I should deposit another $5,000 to get my money. So I tried to login to the account to see my account balance on about June 7. However, I failed. So I contacted Mr. Wu via LINE, but he said some bad words to me. I hope someone can help me recover my money
