Platinum
FRA Airport
booked BMW 3 series touring
received VW Tiguan = downgrade by one category

first the agent wanted to upsell me to 5series, without telling me about additional costs - saw this luckily when she handed over the contract
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.
