I just had a 'customer' of 6 months do a MASSIVE chargeback on me, claiming they were "unauthorized transactions". Normally PayPal allows the seller 7 days to respond and provide evidence for a defense. In this case, they just automatically ruled in the buyers favor and took the money from my account. (wtf?) There's no way I'm going to just accept this given the amount of money stolen from me. I've got proof of every kind that these were authorized transactions, including dozens of email correspondence and his own admission that he's been using the service happily. I plan on filing a criminal complaint with his local police department, then contacting the City Attorney: Prosecutor's Division to formally press charges. Has anyone else done this? What was your experience? Should I expect any results or do I have to write it off and move on?
