Dear SBB Customer Service Team,
I am writing to formally request a partial refund for my SBB Half-Fare Card, as unforeseen circumstances have required me to return to my home country earlier than planned.
I purchased the one-year SBB Half-Fare Card in July 2024. However, due to personal reasons, I had to return to Shanghai, China on August 30, 2024, and will no longer be able to use the card for the remaining validity period.
Below are my key details for your verification:
•Full Name: Jiayi Ma
•Half-Fare Card Number: •••-•••-•••-•
•Date of Purchase: July 11, 2025
•Date of Return to China: August 30, 2025
Given that I can no longer utilize the card for the majority of its validity, I kindly ask for a partial refund corresponding to the unused period. I would greatly appreciate it if you could inform me of the refund process, required supporting documents (if any), and the expected timeframe for the refund to be processed.
Thank you for your time and assistance. I look forward to your prompt reply.
