If you are not happy with condition and the seller does nothing to rectify it,
then leave them negative feedback stating your concerns.
You do need to be a bit careful if you use a magnifier to check condition as
it can over emphasise fine damage that is not necessarily seen by the naked eye.
Many new parts have scratches. Not big gouges, but faint scratches to the surface,
especially CMF parts where someone has felt the package rather heavily to identify
it.
But if it is damage you see by eye, and then use a magnifier to confirm, that's
a good idea.
Neck prints can also be deceiving. Sometimes that print is very low density and
even partially missing. This is not always a sign of use. But if there are scratches
up-down on the neck print, it is more likely.
