How about the movie industry? Do we see cinema goers get all mad because a trailer badly misrepresented the film?
Is that a trick question? Because the answer is "yes" but the rest of your post makes me think you think its "no".
Do you not remember people getting angry at Sweeney Todd being a musical, claiming the trailer didn't make it clear it was? There were reports of people walking out of the cinema on that one.
And that's just one of the more obvious examples that I'm directly familiar with myself (because I loved that movie). There's a whole pile of misleading trailers that left people disappointed and frustrated at the final product. A courtesy google search turns up dozens, maybe hundreds, of articles talking about misleading trailers and customer backlash.
In fact it goes beyond that with the (arguably even worse) issue of trailers being exactly what the film is like but showcasing basically the only interesting parts of the film or even giving away key plot points; which would have been like advertising Final Fantasy VII by showing the scene where Aerith dies. At least games tend not to do that as much as movies do...if only because they tend to try to reveal as little as possible full stop before release.
On topic: Personally I'm on board with making advertising standards much, much stricter. A customer has every right to complain about bugs, broken mechanics, poor optimisation, broken promises, lacking features, etc etc. Why? Because they're a customer. Buying a product. Paying money. If that product does not match up to the expectations that were raised by the advertising of the company due to overhype then they should be due a refund. See as an example: No Man's Sky.
