Can you please help me with Paypal Claim

So, i sold Overwatch+4 other games keys(digital version) for 30 dollars to this guy, we meet on Skype and he seemed nice, and i needed fast cash, Anyway he got the keys and he didn't reply to me. Couple of hours later he opened a claim against me saying that the keys didn't work that an obvious lie, But from what i read on the internet Paypal always sides with the buyer especially with virtual items.
I already used that money, So i'm wondering what will happen since my pp account has 0 dollars, I unlinked my bank account from paypal so i don't think they will ask my bank for that money. I appreciate any help guys, Thank you .

 

The scammer is still not responding to my messages

 

Digital products are not allowed on eBay so you will ain't winning the claim

 

Who said he sold the keys on eBay?

 

Thanks for responding, not on ebay, I meet him on skype, i posted on a forum and he added me

 

Shitlist on the forum you used or out him as a scammer there.

 

Your pp balance will be negative, like -30$.....after some time, if you do not cover your negative balance, some recovery agency will knocking at your door.
And your account will be closed offcourse

 

Yep, done i ratted him out as a scammer, and told everyone to never deal with him

 

Seriously they send it for 30 dollars lol

 

Hmm I don't know if paypal has an minimum amount for this cases but for sure your account will be closed

 

yh that is granted, im gonna have to make a new paypal account

 

Ain't digital products non-refundable (like they're non-tangible goods)?
I remember selling adwords coupons on some other forum ages ago and some one opened a claim against me saying I scammed him, I just replied that the guy talks bullshit because he has no clue what to do w/voucher (more politely) and that I done everything the right way and the claim was removed the other day.
It was 3 years ago so I may be missing something or PP terms may change.
