Maybe it was an overcharge for a station that was down...although I don't think they can even charge you that much for that. There are a ton of bugs in the system. I don't argue over the smaller ones here and there...but certainly would have an issue with a charge that large. Just wish it was easier to report these issues without having to cut and paste hundreds of screen shots and respond to the canned responses that the CSRs provide...when they know less about the system than we do. Also have to wonder why we don't receive more timely (if any at all) responses on here. I would contact your credit card company...which I have had to do every time I try to use an Amazon Citi Bike gift card and they charge my Visa card instead without authorization.
