1) Someone steals his PayPal account and uses it to buy a bunch of stuff on iTunes
2) He reports the fraud to PayPal, which refunds all of these payments to him
3) He reports to Wells Fargo that PayPal has engaged in fraud by taking these payments to fund his PayPal account, which is a false claim -- the transfer to PayPal was authorized as a funding source and PayPal was already handling the refunds
4) Three months later, PayPal gets hit with a bunch of disputes from Wells Fargo to take back money that's already been returned, double dipping and creating major hassles for them. Wells Fargo is, essentially, stealing from PayPal on the basis of this person's old false claim. PayPal flags the account.
So PayPal did everything right: they were available for immediate contact, were "courteous and helpful", promptly reversed the fraudulent payments to iTunes, and his account was left in good standing while he was made financially whole. What more could they have done?
