Japan’s PayPay to update app after wrongful charge complaints — Bloomberg — “An unspecified number of customers called in and e-mailed to report charges on their bills that they didn’t recognize, according to PayPay spokesman Fumihiro Ito. Several consumers say they hadn’t even installed the app but their credit cards were billed for purchases they didn’t make… PayPay triggered a shopping frenzy earlier this month by promising to give users 10bn yen (US$88m) in rebates from their purchases.”
