Item returned - No refund issued

[clarkey501]

Hi.
I have asked eBay to intervene and explained that I have returned a faulty item (I have proof of posting). The seller said in an email Via eBay messages, that they would refund the amount paid. I returned the item but no refund was issued and the seller didn’t respond to my last email.
I asked eBay to intervene. They said they found in my favour and would refund on the return of the item.
Problem is, I’ve already returned it over a week before I opened a dispute. I don’t have it, the seller does.
Who do I contact to tell them I can’t carry out their instruction as it’s already been returned? I’ve tried a ‘return email’ but no joy.
Any advice would be appreciated.
Thanks.

You add the Tracking Number into the Returns Case. Once Delivery or Attempted Delivery is Confirmed you will Receive your Refund.

ruby*tuesday - I don't have a tracking number but do have a proof of posting receipt. Hindsight a wonderful thing on my part. Is this a matter of lose my money and lesson learned as I can't do as eBay ask?

Thank you people!
I do have that reference number on the proof of posting receipt.
Thanks again for your advice.

It won’t accept the ref number.
Think I may have to write this one off. Really annoying as the receipt actually has his house number and postcode immediately under the ref number also!
Oh well, live and learn.
Thanks for your advice guys. Shame I can’t actually show this to someone at eBay. Just hate the feeling of being ‘had over’.
Thanks again and stay safe.
