Samsung Buy & Reward nightmare

I am absolutely shocked and appalled by the service I have received from the buy and get promotion from Samsung!

I had redeemed a voucher worth R4000 in January last year for flights but due to lockdown, I was unable to use the vouchers as flights were suspended.

I called Comair to book flights on 31.12.2020 and I was told that Samsung had put a hold on all flights and I had to contact the call Centre on *** as I needed to choose another reward option.

I spoke to Vuseke and she said it is too late for me to change my reward as there is a process involved and the voucher expires on 01.01.2021. She said she would speak to her supervisor, Wada, as customers should have been advised that flights had been suspended in order for people to know that we had to change our vouchers within enough time. However I was told that it is my responsibility that I did not redeem my flights sooner.

Can someone please explain how I am supposed to book flights when South Africa was on lockdown and flights were not operational for about 6 months of the year, and again how is it my fault that I have to forfeit the voucher when I wasn't even notified of the flights being put on hold?

If this promotion cannot be managed correctly it would be a good idea to stop advertising it and ruining reputable company names in the process...
