Car rental at Hamburg Airport

Cons: Customer care was not interested with us. He just instructed to put the car in the deignated area and he didnt help. Most schocking was, after drop off the car in the indicated location and area, I was exytra charged on my credit card without my consent 23 euro for not known reasons.

Cons: pickup first my car was not available. I was offered to upgrade to higher class for extra payment which i did. when i got to the car it turned out that it was a different car from what i had upgraded to. i took the keys back they explained that the car is mislisted in their computer system. The next car was fine but when I turned the portable GPS on, which I had also rented, the screen was badly broken. Due to the fact that they were understaffed and could not accompany me to the car I had to walk back and forth from the parking lot to the rental desk a few times and wasted half an hour until all their mistakes were corrected.
