RESERVATION | Is the paid reservation cumulated to the penalty for having made a reservations and not taking the car / not canceling the reservation?

Yes. The two are cumulative.

Paying for a reservation does not exempt you from paying the reservation penalty. In fact, according to our current T&Cs, there is a penalty of $5 if you let a car reservation expire without honoring the reservation. We would like to remind that you should always remember to cancel a reservation that you will not be able to honor. If you do so, you will not have to pay the penalty.
