I booked a ticket with SQ - in Class D.

I misread the terms of the ticket and when I cancelled it SQ only refunded AU$166.25.

This is what the cancellation email detailed:

Refund breakdownAUD
Fares refundable4,350.00
Taxes and surcharges refundable166.25
TOTAL4,516.25→
Cancellation fee4,350.00
Total refund166.25

I noticed on the SQ website that there is a page for requesting a refund due to medical or compassionate reasons.

Has anyone had successful experience with this? Otherwise I think I may have made a very expensive mistake!
