I've paid as a gift it won't let me chargeback 
I was googling and I found this for you : http://www.ownedcore.com/forums/mmo-trading-market/general-trade-talk/487839-beware-of-paypal-gift-chargeback.html
If you sent it using Credit card then you can call your credit card company and they will do the Chargeback for you if you paid using Paypal funds I don't think that it will be possible .
