Buyer claiming non-functioning item when it is user (buyer) error

[fish231343]

I am curious if eBay has a history of ever siding with a seller.  In my case, the buyer purchased a wireless charger which I knew from personal use that it worked correctly.  I shipped it promptly.  Within a couple hours of delivery, the buyer requested a refund and claimed misrepresentation of the item.  After a handful of messages between us where I attempted to troubleshoot the issue; the buyer stated that they use a Samsung Galaxy A10 which, according to Samsung, does not have wireless charging capability.  The buyer refuses to acknowledge this as his / her error and the reason whey he/she cannot get the wireless charger to work.  My posted policy is "no returns" but I have occasionally made an exception.  This buyer is very rude so I have denied the claim.  I also noted that eBay does not enable negative feedback of a buyer.  I escalated this issue to eBay and anticipate that eBay will side with the seller even though it is clearly buyer error and abuse of the buyer guarantee.  What is your experience in cases such as this?

If you do not refund voluntarily, eBay will refund him and come after you for their money.

In addition you will get a Defect on your selling account which may increase your fees, restrict the number and value of your listings and may lead to a permanently closed account.

It's business not personal.

The buyer bought the wrong part for his phone. In hindsight, it would have been best to tell him to return it for a refund, which is allowed because this is pretty clearly a case of Buyer Remorse.

She bought the wrong thing, is mad at herself, and is taking it out on you.

As is, eBay will require you to pay for return shipping.

And what you get back may not be workable, if the buyer is angry. Hammers exist.

You still have to refund.

Again, it's business, not personal.

Not every transaction will go perfectly.
