Turbotax Overcharged 2011 Federal Tax Return

I was quoted a free federal return from Turbotax and instead was overcharged for it (I file EZ…did the same last year). Then $39.99 for state was the next quoted price for the federal return for 2011. Well I was charged $74.00, and I could not cancel order, and the fee was not finally disclosed until after payment was taken from me for 2011 federal income taxes. This service is a rip off, instead you should file directly with the IRS Efile if you can. I will definitely do that next year, any one know of a way for me to get my overpayment back from Turbotax?
