Avis bad service, they take the money without given the service

it is unbeliveble how they respond on livechat (where it's not dead). They say something on the web and tell another story where you contact them on chat. The customer care seems to have only 2-3 operators from the names they respond but it's difficult to belive that they are the real names when you see someone responding to you on chat in ecery hour of the day/night
