Case open for item not arrived but item has then arrived faulty. Advice?

[2013alfie17]

Hello,

I recently bought a Nintendo DS with a game cartridge on eBay, the seller took a long time to post out, they said they were away for work, so they posted a week later. Come Friday, I then got a card through the post from the Royal Mail saying that the full postage hadn’t been paid. I had to pay the Royal Mail another £2.50 on top, which I did. 
I’m I wanted a refund for this extra postage cost from the seller so I opened a case saying the item didn’t arrive and that I’ve had to pay extra postage to receive it. The seller agreed to the partial refund but I’ve received nothing as of yet.

It is now Monday and the DS has arrived however I’ve found that the top screen has dead pixels and the left shoulder button doesn’t work. The item isn’t as described, it’s listed as used but fully functional. I’m not really sure how to proceed because I’d like to keep the cartridge and tbh I’d rather not have to return the DS and buy another one but again it’s not as described or fully functional. 
I don’t think there’s a way of opening another case with eBay that it’s not as described while the case that it hasn’t arrived is open and I’m not sure if they let you open one after that has been resolved. Any advice for this would be appreciated, is it possible I just need to try and negotiate with the seller for more significant refund?

Thank you

Well do you still have a case open?

Such should now show that item has arrived if they put in the tracking number to the case;

Wait until it closes then open a item not as described case.

Do not close the case that is open no mater what advice you are given.
