Unauthorized payment increases.

Unauthorized charge increases. This has happened more than a few times already. I book an uber ride, and confirm the payment amount, then after the trip has concluded, the original payment is refunded to my account, and a second, more expense charge is deducted from my bank account. This is ********* and amounts to theft. Taking a higher amount than confirmed with the passanger without their consent should be grounds to call the police on the driver, or sue uber themselves. Companies have been getting away with bull**** business practices for way too long, and it's time for this to change!
