DO NOT BUY/PAY ATAC through their website, do not make any transaction in their website.I paid a bill through their website, and when I looked into my bank account I noticed that ATAC charged me an extra amount of money for no reason. If you call them be aware they will be rude and will dismiss your problem like it's normal extra charging their clients and not having an explanation on why they were extra charged. In my vocabulary that's called STEALING. I sent them emails asking for an explanation almost 30 days later they replied saying: "As for the amount of ? 6.00 there we can not understand where this additional amount comes from and it seems strange that Atac barked a similar request. " After this horrible excuse, I contacted my bank and they rushed to block my credit card. AND if you don't speak Italian, they will give you the most non sense excuses just to make you pay more. Another thing for the tourist, during the summer, suddenly a group of people get into the bus to inspect if all passengers validated their tickets, which is ok till here. If you get into a bus where the machine is not working get out, because they will fine you even though it's not your fault. They abuse of their power as officers, my advice, if they ask for your documents without an explanation call the police (seriously) do not give them your credit card if there is not a notification authenticated by the officer with his/her whole name, the date and time, and the bus route identification. You have the right to record them, if they touch you or your belongs, get out of the bus and immediately call the police and the Embassy of your country. Do not believe in their threatenings, they are the ATAC officers, the authorities are the Carabinieri and Polizia. read more
