Screwed on Paypal ?
 

I have a quick opinion service for autographs.
I have a Paypal link on my website for that service.
The fee is $17.99.
On July 31 I received three payments from an individual.
He emailed three links to me.
All from a questionable auction site.
Not CC.
One Ruth-Gehrig and two Ruth items.
All three items were poorly done forgeries.
I told the person that the items were all bogus.
Today, 29 days later, he files a Paypal case for all three items.
Claiming that it was unauthorized use of his account.
I received three notifications from Paypal, all of which I answered.
I have the email exchanges between myself and this person.
Is there anything else I can do here to protect myself from these bogus charges?

You might get on the phone with them and tell them what happened?

I just tried that.
Getting to a human being takes more patience than I have.
I went through the circus of VM and then held on and held on and held on.
Eventually, I just gave up.
I had filed a response on PP to the scammer and then sent another missive to PP with a further explanation.
