Theweeklypay.com review: Owner didn't allow me to get money and blocked my access

I registered on the website www.theweeklypay.com. I made different jobs for them, and my earnings reached $600. I wanted to get this sum, and I sent the request to the company. After that the company’s owner changed my password and I couldn’t get into my account. I don’t know what to do. Maybe someone has any ideas how to return money back, please contact me then or leave a comment. Thanks.
