Vinted shoe sizing issue; WWYD?

[Epictantrum]

Hi,
I'm new to Vinted so looking for some advice please. DD just bought some trainers. We stupidly only looked at the headline size. When they arrived they were 2 sizes too small because the American size had been stated (6 rather than UK 4). The text of the advert clearly stated women's uk size: 6, which was incorrect. However there were photos of the label which if we had inspected closely showed that the correct UK size was 4. It is quite confusing so I'm sure it was a genuine mistake by the seller. And it was our fault for not taking more time over it and checking all the photos. So my thoughts were to click "everything is OK" and try to resell them. However I feel like I ought to let the seller know as she sells quite a lot of stuff and I wouldn't want her to keep making the same mistake. WWYD? thanks

You could have done in time taken to write this thread

Lesson learned - never rely on the generic classification chosen by the seller - always check the actual size of the item. Ask questions if necessary.

My favourite is when people list something like jeans with as e.g. “Small” with no other information and no photo of label…

Done what?

So shall I just say everything OK and leave the seller to make the same mistake again?

You can contact the seller to see if they would accept a return since it's partly their mistake.
