Last week we visited Paris. On 31TH March we use automatic vending machine to buy 2 tickets \ 1 adults and 1 reduced for kid / from Charles Degaulle Etoile/ closed to Arch de Triumph /to Disneyland.
Yesterday I reviewed my account statement and saw that you had taken us different prices on the way out and on the way back. I'm sure the price was the same. But for one of the directions, you charged us as 4 adults???? How is that possible?
Different prices for one direction with RER
