Quoted from KHL:What's even lamer is I can't pursue a claim because I messed up and sent the money as a "gift" on PayPal, just have to hope he's honest but I'm wondering if anyone has dealt with him and can advise me here.
As long as you used your credit card to fund the PP transaction, you can do a chargeback directly through Visa.
That's why you NEVER want PP linked to your bank account. Anyone who has that connection needs to un-link it, RIGHT NOW.
