This happened to us when we went through a toll we thought was abandoned - really run down, no people about & no barrier - goodness knows where the blooming camera was that caught us going through it - funny thing was we stopped and deliberated for ages what we should do but considering there was no charge details or anywhere to put money we carried on!
Dollar took the $18 fine direct from our card and sent a letter explaining why, I would be cautious sending payment off with your details to anyone other than Dollar and this I would do over the phone with them after checking all the details.
