If it were me and I bought something on ebay and they sent a different one than pictured, I would send the SOB back, whether they claim they allow that or not. If nothing else I would contact the seller and demand they either refund part of the money or you are sending it back. If you file a complaint with ebay stating that it was not as represented, I think you will get ALL of your money back - at least I have when this type of nonsense happened to me in the past.
*** For casual readers of this site --- This is why it is often better to buy something you can hold in your hand and look at, perhaps paying a little more, than buying it on ebay.
