Bought a mobile phone off ebay that was incorrectly described - help?

I bought a mobile phone recently. The entire description stated the model is a C905 but when I received the phone it turned out to be a C903.



I contacted the seller who admitted her mistake, and agreed to return the item for a full refund. The seller does not want to refund postage fees. I understand that in most cases you don't get p+p back but this seems unfair seeing as though the seller incorrectly described the item at MY COST.



What is the right thing to do?Bought a mobile phone off ebay that was incorrectly described - help?If the seller listed it wrong it's their fault, even if they have something about that in the terms and conditions. Don't pay for postage, if they make a stink about it file a complaint with eBay. Threaten negative feedback if you have to, they won't want to lose reputation over a couple dollars.
