Tax Attorney review: Took my money and did nothing ! 1

Segal, Cohen & Landis, LLP Samuel C. Landis, took my money $ 7, 050 and did nothing for 12 month but file a power of attorney !
I paid Mr. Landis $ 2, 500 initial payment plus $ 350 a month for 12 month.
I called the FTB and IRS directly to find out why my case was not settled. I was informed by both agencies...the only paper work they receive from Mr. Landis office was a power of attorney.I sent Mr. Landi's office hundreds of documents and tax returns to forward to the FTB and IRS and according to the FTB and IRS they were NOT receive.
I ask Mr. Landis to honer the guarantee that he gave me in writing...He did absolutely NOTHING !
I asked for my money back in writing three times...My requests were IGNORED !
I paid $ 7, 050 for someone to file power of attorney...TOTAL SCAM !
BEWARE ! DO NOT GET RIPPED OFF !
