You only have 30 days from the last estimated delivery date  to open an item not received claim  through eBay's Money Back Guarantee and looking at the listing, I think you may have just missed that by a day  or  two - hope I'm wrong

If it's not in your purchase history, did you purchase as a guest  ?

Or through social media ?

You have 180 days from payment date  to file an item not received claim with Paypal,  if you paid that way.

Or you could try a chargeback through your bank

You need to open an item not received case immediately. 

Well over a month ago, so what was the estimated delivery date?

How long did you wait before attempting to do anything?

Have you changed the drop down menu in your purchase history?

Have you communicated with the seller? 

Did you buy on this account or as a guest?

Seems very sus that the same seller has sold the same stove twice and the photos are lifted from another site

Screams scam

How did you pay?  (pay pal, bank deposit? credit card?)
