The Tax Group/ Proggressive Tax They Must Be Stopped Calabasas, California

This truly needs to be stopped, from stealing folks hard earned money, they pray on people in need of help. I hired them to settel back taxes with the state and IRS, in the course of them handiling my case I never once have been able to speak with a attorney, I have had to do several different contracts with them inresulting paying them more money each time. After 16 months of them working on my case with no results they called and needed more money, at this point we were told they were just about complete with the settelment and they had more billable time involved to complete the work, They then sent me a new contract Stating NO FUTHER CHARGES to complete the case. 
They sent us the documents to sign for the agreement with the state witch we had send in back in with a down payment, then they sent us a offer and comprimise for the IRS to be sent back with a down payment. At this point we thought every thing was great, Then the BOMB drops A revenue collector from the state call's with a curtusy call to let us no that our power of attorney isn't returing her calls and our pay checks are going to be leveid becouse what the tax group had us send in was just a offer not a AGREEMENT and the offer was DENIED..
Then The IRS needed more information needed more information on there offer, so of course the tax group call's looking for more money, I reminded them they gave us a contract stating NO FUTHER CHARGES and I was told by Chris Gummerson they were handling the situation.
Now at this point I have nottified from the IRS that intend to seize my property, becouse I never responded to the information they requested. This is due to them not onering there contract.
I have had to make my on arrangement with state for double the payment amount of the taax group had given me in writing, now I have had to hire a attorney to take care of The IRS so I don't loose my home and property.
I paid this scam company Thousands of dollars for nothing. They will not take our call's or answer there e-mail or return there messages.
Please help me stop this company I have attorney ready to take the case but we need more people to come forward, send me a note and I will put you in touch with them.
I have contacted the California attorney General and the FTC , but I need to recover some of money as I am sure you do as well, please come forward Let's stop these crooks.
