www.centinary.com is very very big fraud company

I have been trading with Centenary Trading Company for four months. I had up to $3000 in my trading account. Suddenly one day they said it went into the red. They loaned me $13,000 when I was already aware that I had lost $3,000. In this situation, I had been trading for the past three months and had $496,000 in my account. I ended up owing $7,000 of the $13,000 they gave me. They are still telling me that I need to pay $5000, but suddenly my trading account has a profit of $496,000 and it has been in the red for the past three days.
