I am a loyal Hertz renter and because of my UA 1K status I got Sixt Platnium so gave them a shot a few weeks ago in Berlin. I got a nice BMW (happy with car) but then returned at FRA....now my problems start! Took 15 minutes for agent to get to me, another 10 minutes to go over the car and then in very, very bad english says ok and have good day. I asked for final invoice and he goes away for another 5-10 minutes then comes back and says no he cant provide one. Ok I figure walk away and now there is 196 Euro fuel charge on my bill!!!! I filled the car to the rim 1 hr before at a cost of 71 Euro and am waiting for instructions from Sixt where to send copy of charge it but no word back yet from them.

Has anybody had issues like this with Sixt? I rented one other time a few years ago in Spain and it was fine. I am just blown away they cant/wont provide a final invoice from the handheld device or at least take you inside for one.....is this the norm?
