Optionsxo aka DOLCE FORMULA LTD Optionsxo.com is a Forex Trading company and they will not give me my money that I earned. London Internet

I live in the United States, in the State of Oklahoma and I made an investment of $2,000.00 to www.optionsxo.com which is a Forex Exchange company based in the United Kingdom, via my credit card and I earned a profit of $7,000.00 and I have tried to make several withdraws of $2,000.00, $1,000.00 and $3,400.00 respectfully. To the present I have waited over two weeks for them to pay me and they always come up with an excuse. All they want me to do is invest more money and tell me not to worry about the wire transfer of my money to me. Optionsxo is located at Building 3, Chiswick Park, 566 Chiswick High Road. London, W45YA and their phone number is UK +44-203-404-5709, Fax: +44-2033265534, which you can never reach anyone. They are also called, DOLCE FORMULA LTD.
