I can only speak for Norway, but this doesn't normally mean reversing the charge. It's assumed that, if you bought an X, you wanted an X. So the seller is required to get you an X of good enough quality to actually do the job, and if that isn't what they were trying to sell... well, then they won't be in business for long.

Normally this means repairs or replacement, of course on the seller's bill.

The US seems much more geared to seeing every interaction as... I want to say 'combative'.
