Sounds like somebody should stop going to Hunter
Seriously, if you're not getting the right fit from your boot, when you were promised "Free fitting" and you're not getting the right tune on your skis when you were promised "Free sharpening" (hmm, Sharpening != Tuning IMHO), maybe you should be basing your purchase decisions on something other than "Free".
Pick a good ski shop with a good bootfitter. Take your time selecting the right boot and know what a good fit should be. PAY for custom bootwork and footbeds. PAY for a season-tune card from a good ski shop, or pay for tunes as you need them. ASK the shop questions. Rick Reiter/Vail SnoPro did a fabulous presentation at EpicSki Academy this year on just what sorts of things you should ask and tell you tuner - probably there's some summary in the Academy or Gear threads.
Nothing personal, and obviously I don't know the whole story (in part because you only trickled it out as a hypothetical rather than coming out with just what your problem was), but you sound like you're setting yourself up for a lot of bad experiences by not researching your choices enough. And by letting price take precedence over quality.
Good luck with working this out. If you honestly feel you were lied to by the shop and didn't get what they promised, then dispute the charge with your credit card company stating exactly what they promised and didn't deliver. If it's a reputable issuer like Citibank or Amex especially, they will alway at least initially take the consumer's side and put the burden of proof on the merchant. Their cards are more costly sometimes, but again, you get what you pay for. Didn't use a credit/charge card for a major purchase like this? Then you gave up a major consumer protection option.
