Seller refuses to send me a return label

[thetrinketseller]

I received an item from a seller that turned out to be faulty. After providing pictures of the item and opening a return request with eBay, the seller agreed to let me return it.

However, the postage label that they provided has expired before I was able to post it due to Christmas opening times.

Now the seller is refusing to provide another label, and eBay are saying I need to return the item before the 7th in order to receive a refund.

I feel like I'm stuck between a rock and a hard place here. What can I do, other than cover the cost of return myself?
