I've gone through exactly the same by purchasing an item in error, my bad I didn't check the seller's registration from a Chinese seller.
Couple of things here. Your item's location you say is Manchester, then don't be fobbed off that it goes back to China, it doesn't, it goes back to the UK location, Manchester. Send the seller a polite message to send asap the appropriate postage label for the UK, for the return of their item. This is important, because I feel you'll need to contact Customer Services like I had to later.
I was asked for my PayPal details, if you're asked, umm it's no again, send a polite message this is not in eBay rules, it's not needed, ask again for a label they need to pay for.
I waited over 6 days and the option to escalate did not appear. I had no label, and no refund, and no escalation option !
I'm thinking if a seller sends a Chinese address for some reason it fools the system thinking a label is sent and the option to escalate does not appear.
I contacted CS they viewed the case, viewed all the messages, and refunded me and closed the case telling me I could keep the item, I kindly informed them the item's new home is my bin.
Disappointingly, I received a discretionary refund, meaning eBay repaid me, and they told me the seller gets to keep my money too! The seller after all was selling in their thousands.
You may well experience the above certainly seems to be heading that way , in which case you may well need Customer Services later.
The easiest and quickest way to contact Customer Services is through this link, for a Call Back .
