Hello @saa
First of all, I would like to inform you that we also have an English community. Maybe an english speaking user has the same question and could get also the answer to his question. Just change the language of the page and you will get into the english community. 😃
You cannot deposit the seven25 subscription. If you wish to return your seven25 annual subscription within the validity period, you can have it refunded at public transport sales points or by calling the SBB Contact Center on 0848 44 66 88 (CHF 0.08/min.). The refund is calculated as a percentage of the number of days used. A deductible will also be charged. (You cannot return the seven25 monthly subscription). A deposit/pause is only possible with a GA travelcard.
Thank you for your understanding. I wish you a nice day.
Kind regards, VlaznimA.
