We just received a notice from Hertz charging an administrative fee (noted as a "parking fine"). I think the fine might be from our toll for the Dartford Crossing. I thought we had paid this toll correctly. We went on the internet and registered our rental car. We paid a toll by credit card. I did this before we crossed, so was I supposed to register the time and date we crossed after the fact?
I don't mind paying a fine if we did this wrong, although it's a little frustrating to pay a toll and pay a fine too. I seem to have thrown out all our receipts from our trip (in an effort to get rid of clutter!), so I don't really have any documentation that we paid, other than what shows on our credit card receipt.
So, I'm wondering, what is the correct procedure for paying the toll, in case we ever do this again?
Thanks
