Goithoambi10 Hi, i bought 2 half fare card but selected wrong start date. Can you change for me please?
Ein_Albaner Goithoambi10 Hi If you purchased them on www.sbb.ch/en then you have to call the SBB Contact Center on +41 848 44 66 88. They will exchange you the date of validity or refund it to you back and you repurchase it for the right date of validity. Have a good day.
