Has anybody been charged for making a reservation and not cancelling it?

I have done it multiple times but could not pick up the car due to airline cancellations or family emergencies. I have never been charged for that.

Last week, I made a reservation to pick up a car in Vancouver but did not get to Vancouver in time. However I forgot to cancel my reservation. Yesterday, I saw a charge on my card on-line from Budget for the car I never picked up.
Do I have any chances to dispute this charge?

TIA,
