What I'm trying to say is that the Return Policy details is meant to outline and clarify the terms of change of mind returns, not what happens if an item is not as described, as well as what will be provided for change of mind.

You can state No Returns on a listing, this doesn't negate the buyer's normal consumer rights for a refund if something is not as described - those rights are a given, therefore there doesn't need to be any specific terms outlined for them because they're already in place, that's why the return policy details can state things like that only merchandise credit will be provided, only within 7 days of receipt of goods etc etc, because it's to detail A) if you will accept change of mind returns in the first place, and B) what the buyer needs to do to be eligible to return the item.
