Problem to add my pass on my mobile phone ''details don't match''

Hello ! I bought 2 mobile pass but I am not able to add them on the app. It says « your details don’t match ». I tried to reload and reload the app or to add the passes on another mobile phone but it still don’t work. I am supposed to travel, within a few days everything is planned but the customer still don’t answer so I can’t book my first travel. Is someone able to help me ? Thank you very much !! Mélanie.
