I agree, buyers fault. Buyer needs to be more direct on what he needs. Part #, more precise on his needs or application. Saler, may not have all the answers, so buyer needs to do his due diligence. Buyer should send back on his own dime, as well pay the original freight. Saler will refund the balance after any of other expenses taken out. This is the reason I don't ship. Packaging, postal fees and the trip to send.
