I've been screwed over countless times by companies. (We probably all have...) In the grand scheme of things, $45 isn't that much. Yes it sucks, but IMO, definitely not worth letting it raise your blood pressure and getting angry about.
One of the nice "perks" of having FU/FI money is, things like this, while definitely suck, aren't going to ruin your budget.
Just add all companies involved (QVC, that "chef", the manufacturer, etc) to your "never do business with again" list. I keep a list of such companies that are "dead to me permanently."
