Last time I booked a car with Avis more than half a year ago. Now, on February 20 I've found -42,70 euro from my card missing with description "AVIS MILANO MXP". No explanation sent to my email, no phone calls - just nothing, they just stolen my money. Be aware and always check your credit card's accounts!
I have sent them a message through their web site, but no explanations for three days already. I think I should initiate chargeback through my bank now.
