Mortgage Relief LLC took money to reduce my mortgage and has done nothing and I can't get ahold of them. Scottsdale, Arizona

In April of this year ther was a commericial on the TV over and over and I thought it was the one that Obama was involved in reducing mortgage so I called Mortgage Relief. The commercial made it seen like it was connected to the government stimulus thing. So I called and sent $1000 to get my mortgage reducted I was suppose to have more taken out of my account but I had to change my bank account so they didn't ripe me off for the full amount. Anyway I never heard anything back from them so I started e-mailing them and calling them at first I could at least get ahold of someone but they nevery called back to give me a progress update, then I got an e-mail with a new address  and I talked with someone once and now knoweone answers the phone and the fax machine doesn't work either. They don't respond to any of ny e-mails. I have started to request refunds of my money but haven't gotten any response.
