Complaint Review: tax defense network

I contacted this company from a phone ad in the local directory, the sales staff convinced me that they would help resolve my tax problems, which was a garnishment of wages, remove the need for filing unfiled tax forms, and reduce my debt or completely remove it.  The only thing they did was file a uncollectable status, filed four tax forms, which one of the years will have to be amended. 

Now I have the IRS is demanding payment for just one of the years, which I am sure other demands will come.  I've contacted there grievance department, and was told that was all they could do.  They have done all this wonderful work at the tune of $4000.00. I could have done the same thing in about probably in a hour and half.  Now I see how attorneys live the way they do.
