Missing Bike

I'll keep it short.  About 2 weeks ago, I was angeling at night, took a bike out and docked it properly at a station, as usual.  However, it did not register docked so I took a picture of the bike and station, reported it, and ended the ride so that I can continue.  However late next day, citibike said that my bike was not docked properly and charged me for 24 hours.  The bike# they said that I docked is not the same bike# in the picture I took.  Now citibike is charging me total of $363 for missing bike.  I tried to explain as Citibike Angels, there's no reason for me to take a bike, and not dock it properly, because that's how I make the points.  I was wondering if anyone can direct me to someone at citibike that can help me out.
