If a buyer is asking for a return because they didn't read everything, Ebay will still expect you to accept the return if the buyer states the item is 'not as described'.
Is that what you needed to know?
More detail and a more specific question with some context would lead to better advice.
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
