Horrible experience with Europcar!

Horrible! Rushed out upon arrival as didn't want the counter staff to wait too long. Keys were provided, told where to go and rental agreement signed. Was not shown to the car to perform checking of the car together. Just asked to take photos to protect myself. Upon finding the car, realized that car seat was not installed or even provided although I already remarked in my booking. Went back to the counter which was already closed and empty. Amazing that no one among the other car rental booths had the Europcar employees mobile number and no number was left pinned somewhere at the counter. Called the careline who made me wait so long on the line (I was on international roaming!), arguing with me (WHO WAS IN FRONT OF THE COUNTER) that the counter at Avalon should still be open and finally telling me they couldn't do anything. I needed to get another car seat from another Europcar branch the next day! A TODDLER TRAVELLING WITHOUT A CAR SEAT IN AUSTRALIA IS ILLEGAL!!!! Luckily for me, the staff at Hertz next door saved my day by obtaining a spare car seat for me! First and last time renting from Europcar.
