Last year I bought 4 tickets on SAA from JFK-JNB for Pesach. Then there was this thing called Covid-19 and all flights were canceled, and I requested a refund for the flights which did not even take off even if we would have wanted to travel. They did not respond to the refund requests (by phone and email) and so I disputed the CC charges and was refunded in full.
More than a year later they finally responded to the email, and are offering me a refund in the form of an SAA travel voucher. Now, it is entirely possible that after I fill in the voucher request form they sent they will pick up that the charges were refunded. It's also SAA, which has the competence level of an average journalist reporting on frum Jews, so more than likely not. It is also entirely possible that SAA will never fly from JFK again and I will have no use for the voucher.
I think applying for the voucher is kind of stealing, but I'm being told by some I'm crazy and I should absolutely fill out the form, and if they send me a voucher, it's on them.
