So i want to do a paypal Chargeback from a website. I have done so many chargebacks before and non has failed. BUT i don`t know how hard this website is to refund from. What is the best way to make a 100% success rate on a Paypal chargeback ? The "unauthorized activity" or "I didn`t receive an item i purchased" ? I have never done the "unauthorized activity" so is it hard to do ? Thanks!
