Get your taxes done using TurboTax

how do you actually speak to a person at Turbo Tax?  I needed Turbo Tax Business, but I mistakenly upgraded to Turbo Tax Home & Business (based on the fact that Business was in the name I thought I made the right choice) but Home & Business is not what I needed.  So I paid $40 to upgrade to Home & Business which isn't what I want, and now I've paid $140 additional to get Business.  I'd like my $40 to be refunded.  I'll pay the $140 (which I did) for Business, but the other $40 should be refunded, but I can't figure out how to talk to someone!!!  I guess I'll just have to dispute the charge on my credit card if all else fails.
