TCF not exercised

I have been reading through the terms and conditions of my contract of which states that each successful Makro card applicant will receive a R100 birthday voucher .

Reading through a number of the complaints, most reasons for the clients not receiving them is due to them not being subscribed but nowhere does it mention that you need to be subscribed to receive your voucher.

My birthday was on the 20/01/2019 and surely my voucher which was not sent to would still be valid by today, therefore I'm requesting for my voucher whilst it should still be valid.

I have seen a number of vouchers provided still due to the complaints so I'm assuming with my birthday having just passed, it shouldn't be an issue to have mine given to me.
