State tax filing

I just got slapped with a $700+ bill  bc Turbotax screwed up my tax return.  And I can't talk to someone at Turbo tax bc I filed for free and only paid customers get to talk to a human.  This is their mistake!  I shouldn't have to pay them for the privilege of talking to them to ask them to fix it.  I am so mad right now!  I didn't even get my tax return, bc my student loans garnished it.
