Been wanting to post this...
Sixt FRA
Gold
Booked CPMR
Received CDMR ... 10 day rental
One way rental drop MUC

We arrived at the counter and were told we had been upgraded to IFMR(Peugoet 5008) I refused kindly as we were going to stay with friends in the Alps in a little village with small roads so no SUV was needed. Clerk at the counter said only CPMR was a 116i. My husband and I said that was perfectly fine. He would be doing most of the driving anyways.. After a few mins the clerk said the 116i had a block on it and suggested we take the SUV again I said not needed this time. The clerk says well I don't have any other cars except an Astra or the SUV... After some back and fourth it was basically take the Astra, Pay 200€ more for a 3er or nothing. We were disappointed and ended up taking the Astra. Not the class we wanted but small enough for small roads.

Once we arrived at our friends house I casually checked my banking and saw that Sixt had billed my Visa twice once for the CPMR rental and Once for the CDMR rental.. while it didn't put a strain on us traveling it just made an already sour situation worse...

We have a wedding in Orlando in November and are debating avoid Sixt all together
