us doc assist llc they took my money and have not called me back or answered my emails phoenix , Arizona

I paid  them 199.00 and they sent me a letter  and  then I sent them emails and tried to call and I get no answer nor no return emails or calls. They then did call asking for $2000.00 dollars to get leads and I told them that I had nothing to give them and they said when I do get $2000.00 to call that they need to fee there children.. I have not heard from them in two weeks and when I send them leads they do nothing at all....I want my money back.  If you could help please do so or let me know what is going on thanks so much
