obviously I refused then she said - you have to wait some 45 minutes as I cannot give you the upgrade for free
found a Tiguan, I accepted as I had an urgent appointment
called customer service hotline - they said you only can claim to a lower price, when the rental is finished
I've asked for providing me the class I've originally booked and she promised that somebody would contact me - 30 hours later nothing obviously has happened
I think there are other agencies out there - never had such a ridiculous attitude towards a customer regardless if there is a status or not.
quick update. Still nobody contacted me, although the agent told me my correct phone number, which was on file. This shows me that Sixt currently only tries to screw their clients.
Upsell without asking happened to me before, but there I've realised only when I returned the car.
With such a customer approach I can only warn everybody to use Sixt. However I'm not sure if the grass is greener on the other side. Or in case it is, its only because it rains more often.
