I had someone who tried to scam me as well
Sold him a $950 Radeon VII video card.
2 months later he messages me, says it doesn't work. I said, you've had it 2 month, and now it doesn't work?
He said he didn't get around to trying it out until now. BS I said.
Long story short. We went through the whole scenario of me refusing the return, him filing a refund with Ebay and Paypal.
Paypal sided with him, and I received a negative balance in my paypal account that they demanded I pay.
I messaged Paypal, told them that they have now become the owner of a Radeon VII card. And I will never pay the balance on the account even if they try and take it to collections. And since there are now several other online payment options available I would never use them again.
Now, given that I've spent a lot of money through Paypal, I guess they decide to eat it. They rolled back the negative balance.
However I'll never sell anything expensive on Ebay again.
Especially now that everything will be going through them, including payments..
