You could return a bag of rocks at this point
I am exahusted, I end up with a lot of rack pull gear through my company and its nice to make a few extra bucks on some old gear that we would otherwise pitch - I don't do it at the rate I used to but I still sell things from time to time, I sold a fairly high end netgear switch that worked perfectly fine - it was only used for about a month and sat powered off in a rack. I did my normal dance of prepping to sell, did a 24 hour burn test - verified it worked and then packaged it up and shipped it off.
The buyer sent me a note after it had shipped asking to cancel and said he discoverd it wouldn't work with his system, I said sorry it was already shipped - my store doesn't allow returns. He proceeded to put in a return request for damaged item, it was instantly decided in his favor without me being allowed to even send a message (Thats a new feature... I remember it used to take two weeks to lose as a seller).
Fast foward to today, I got the "Switch" back and he swapped it out the same item but a difrent serial number, and its clearly a phsyically difrent item then i shipped him. It doesn't power on, and is a brick. I pointed it out to eBay support, they opened a case and instantly closed it saying that I reeived the item back and they are entitled to a refund at my expense.
Whats to stop me from just going and buying a bunch of 2k items and returning a bag of rocks? its like they don't even read cases anymore.
