I am not sure how you got such impression, since I clearly said that we made an actual booking for CPMR, we did not 'look at prices' for it. Therefore, had the information about travel restrictions been communicated properly, we would have just kept the original 100 euro booking and not been forced to make a new, 50 euro more expensive reservation.
In my opinion, just because the issue in question is not unique to one car rental company, it does not make it acceptable nor should it stop the customers communicating that this is an inconvenience or suggesting a potential solution.
