PHILADELPHIA (CBS/AP) — Ride-hailing giant Uber is blaming a computer glitch for overcharging a “handful” of customers, including one Philadelphia woman whose bank blocked an attempt to charge her more than $28,000 for a ride.

According to Philly.com, the woman first said she got an email from Uber warning her that her financial information had been hacked. Six days later, Uber sent another email telling her that was wrong and that Uber’s engineering team was aware of the error and fixing it.
