Perfect Tax Relief Took my money and no action in 2 years Los Angeles California

I applied for tax relief back in 2013 with perfect tax relief. I paid the fee of 2500 for help. II gave them all the required documents and they stayed in contact with me until all the fee was paid. My agent her name was Marcela and said she was waiting for the agent from IRS to contact her. So we played phone tag for a month. Finally I got in touch with her and asked what was going on she told me the same thing. I asked if I could get a refund and she said no. I said I wanted to speak to her supervisor and was told one was not available. She then said she would try to contact the IRS agent again and get back to me, well that was 6 months ago.
