Seller will not respond to a return request.

Open a case. If you already have, ask eBay to resolve it when that window opens.

Read the information on the eBay site about how the Money Back Guarantee works.

You've been a member for 19 years - surely you have worked out how eBay works in that time!

What happened?

You need to open a dispute within 30 days of receipt of an item.

There is zero onus on seller to do anything without a case.

Ebay has the tools you need - please use them!

The ball is in your court to open a dispute and follow through with it

Unless you want to return something because you simply changed your mind and the seller does not accept change of mind returns

There is nothing other members here can do

As said, you have been given all the tools, you have all the power

The seller does not need to 'respond' to you for you to act
