Typical sales should include full disclosure in description and pictures. So in general, the answer is yes if the sales were misrepresented intentionally or accidentally or however then absolutely. But I would see that as a last option....you have to try to work it out and I think that is what OP tried to do. It would have to be agreeable to both to make it work. In this case, seller opted not to and offered full refund. It can't get any better than that.
