That's just how e-bay is....take the refund and get the item back but don't pay the full amount like they said and have them send the part back. When listing something for a auto say the drive front blank or driver back blank and so on. Because if you are in the car the left is....on the left but if you are out of the car and standing in the front looking at it...the right is now the left.

In short some buyers on ebay are just not smart and wont read the whole ad....you just have to deal with them the best you can...at lease this ebayer knows its not your fault its there and will take a part of a refund.
