Escalating closed case

[Parker29]

I spoke to the seller who agreed to a refund as the item was unopened. I returned in original packaging, AusPost shows delivered 19/10/2023.
I have since rang and emailed Seller. No refund provided. No response to emails and now no response to my mobile number.
I escalated to PayPal.

They reviewed the case and then closed the dispute saying : "The case was closed because the transaction was processed correctly".

I don't have the $550 item I paid for and I don't have a refund.
How can I have my case re-opened / escalated?

Paypal covers you for non receipt of item OR item received but not as described, anything else ie buyer remorse is between you and the merchant.

So which dispute did you open?
