eBay doe not try to keep sellers happy, eBay is all about the buyer

What is happening is the same thing that has been happening for decades

You did not look at the sellers feedback

or the estimated delivery date

Both clearly and easily available

You would also know that buyers cannot cancel

The country the seller is registered in is on their feedback page

Along with the pages of negs

But even without looking at those

You still had the estimated delivery date and the shockingly bad feedback in front of you on the spot

Even the screenshot you posted shows how garbage the feedback is
