Hi fortesp
Thank you for your request.
I don’t quite understand if you have a monthly or yearly Mobilis Pass. The refund of a monthly travel pass is possible up to 7 days of use. For annual passes, it depends on the number of days used. It’s not possible to interrupt these types of Pass.
For further information, please contact us by phone to 0848 44 66 88 (CHF 0.08/min), my colleagues will tell you about the possibilities you have.
I wish you a good weekend.
Regards
NicolasK
