Unfair Charge

I have used the free program from Turbo Tax for years because I take a straight deduction. Don't mess with iteming any longer. This year I sold my one and only share of stock that garnered me a whole $29 in taxable income. For this Turbo Tax charged me $ for64 state, $209 for federal, and $40 service fee, total of $313 to file my taxes. I could have had my taxes prepared by a live certified accountant for less than what I was charge for reporting the sale of one single share of stock. How can I get this ridiculous charge reversed and get my money back? I wrote to Turbo Tax at the Tucson address but have, so far, heard absolutely nothing in response. Can you help?
