If this were a shop and you bought something new from them, then yes, they would have to give you everything that was advertised and you paid for. Regardless of how much it would cost them and how much you paid for. Unless there is a disclaimer in the ad that says something like: "Item may differ at sellers discretion without notice." But you bought off of Ebay. Read all the legal mumbojumbo on Ebay, I do believe that there is a caveat about what you put in the ad must be what you are selling. Plus, there is feedback. You should check it from who you buy from as well as don't hesitate to leave negative feedback after you have tried to resolve the issue.
Remember, a couple of years ago, people were advertising X-box's just before they came out. Lots of people paid a lot of money to get these. What they got was a box with an X on it, exactly as it was worded in the ad. To this day, you still see people selling pictures of high end markers, cars, motorcycles and such. People think that they are getting a DM5 for $100, and they are highly ticked with they find out that they paid $100 for a picture of a DM5.
