Unexpected charge of 1100 euros with no response for a week

The car was not what I booked. I reserved a Passat wagon, but they gave me a Touran instead and insisted it was the same class. I was in a hurry and didn't argue further.

They pushed additional sales, the staff's English was not good and they were discriminatory towards customers. They couldn't accept UnionPay cards, downgraded my vehicle, and maliciously charged me without any explanation even 20 days later. AVIS in Switzerland is extremely bad. Do not choose this company. This is the worst car rental experience I have had in years of renting cars abroad.

Ask for upgrade and was turned down. The customer next to me was given a upgrade without he asking. The car had minimum level of windscreen washer fluid. Had a a hard time to drive in winter n snow without washer fluid. Bought my own windscreen washer fluid to top up and use for my driving in winter snow. Avis disappointed me.
