Hello! My family plan to take trains from Zurich to Milan, We have already ordered the trian from Chiasso to Milan and bought seat reservation as well. But when we purchase the seat from Zurich to Chiasso, we found the seat number as given at random. I say the regulation that the seat reservation can’t be refunded or changed, But still want to find a solution. Anyone met similar situations like us? How could we do?Is that ok to directly settle down the seats we reserved from Chiasso to Milan when we are from Zurich to Chiasso?
