Samsung MSC voucher - Misleading consumers!

In November 2017 my husband took the Black Friday special from MTN for the Note 8 which came with a R4000.00 MSC Voucher and Samsung 32" TV. (I won't even go into the struggle we went through to get the TV)So we were told to download the Rewards app and claim the MSC voucher from there and we need to use it within 12 months. Nowhere on the rewards app screen was it stated that we need to redeem the voucher from the website by a certain date. It still shows “Status: AVAILABLE” and “Expiry date: 15-12-2018”. So now wanting to book a cruise we went yesterday into the app to get the voucher and clicked on the website but it just shows a picture and nothing else. So we email the Samsung reward help and after back and forth emails they tell us the following

“As per our Terms & Conditions, we are unable to assist you with your claim as this promotion has ended on 15 January 2018 already and all claims had to be done before the campaign ended. This was a two part claim. The first part had to be done on the Rewards app to receive the voucher code; you then had to enter that voucher code into the AroundSA website in order to receive your MSC voucher.”

How frustrating was that to read!! I do not accept these terms and conditions! Clearly you are enticing the consumer to purchase your brand of cellphone and offering them the rewards for it but mislead them by not displaying UPFRONT by what date you need to claim the particular reward, but only embedding it in your terms and conditions. This is so similar to the Glocell **** with the MSC voucher which many people never receive either.

I feel this is really unfair on the consumer and we should still be entitled to this voucher
