Hello Kacheungu75
Here on the SBB community, we cannot assist you because, for privacy reasons, we do not have access to tickets or refund requests. Also, for data protection reasons, we advise you not to post personal information here.
Therefore, I recommend contacting us by phone anytime at +41 51 225 78 56 or writing to us via Live Chat.
Please remember that it takes at least 5 days for the refund request to be processed and, if accepted, a few more days to receive the money on your payment method.
I wish you a great day,
Chiara_S
