Problem with seller about a refund

[dlking58]

I have a problem with a seller.  I purchased a 2 large rolls of elastic for making face masks.   The black elastic was good quality.  The white elastic was flimsy and cheap.  After a few days I decided to contact the seller about a refund.  This was in May.  The answer I received was polite and promised a refund. 

However, after a couple of weeks I didn't get the refund so I contacted them again.  This has now been going on for weeks.  At point then said the refund would be done if I promised to not post a negative review, and I agreed.  Still no refund.  I have been receiving weak promises of a refund since April, and the last time, (this week) I was told it would be done with 3 days.  I know I should have been more aggressive, but I knew they were probably experiencing problems just like everyone else.  The person who was responding was nice, but kept referring to a "partner" who had to do the refunds.

The 3 days came and went - my last message was that I had waited long enough, and I was going to post a negative review for not only the product but the poor customer service if I didn't get it immediately.  I received a flippant message saying:

"Of course you can, I will commit suicide tomorrow, whatever you want".

This was obviously not from the person who had been so nice, but presumably from the "partner".

I immedately responded back saying I was very disappointed in this unprofessional and immature response, and that I was going to contact eBay, which I should have done a long time ago.  In response I received two messages:

"what a shame ,your order is right,but u are disgusting and gready"

and " Dear friend，I will check it with my partner and record it for you. I will do my best to solve it for u after checking it, ok? It’s really my honor to serve you. Best regards"

At this point, all I want is to leave negative feedback about the product and the customer service, but when I look at the eBay site, there is NO WAY for me to do this becaue the order is outside the date range for doing that. 

Is there anything I can do?
