Europcar - Santa Cruz De La Sierra International Airport Viru Viru Information, Car hire Instructions & Policies

First of all that the counter staff wanted to charge me some extra money for "online booking fee" that was not informed at the terms/booking confirmation. The car has a speed limit alarm when reaching 80 km/hr, and it had kept on sounding the alarm all the time when I was on the road, which made me have a really bad time experience, since the speed limit on road is 110km/hr. My flight was rescheduled, so I called at the car's drop off location in order to confirm the working hours, and the staff informed they open always at 6am. I arrived there at 5:45am and waited until 7:00am and no one showed to open the location. There was no instruction how to proceed in this case, and I almost missed my flight because I did not wanted to have problems with the car, since there was a value blocked in my credit card. After waiting there for so long, and afraid to miss the flight, I contacted the cell phone that was informed at the office glass, so Rodrigo, really nice guy, instructed me to leave the car key at a box outside the office. I am very thankfull for his atention, but I believe it is not professional, once the office does not comply the informed working hours, and even there was not instructions there to proceed in this case... So I really had a bad time renting this car.
