Reward still not allocated

Early in December of 2021 I won an upgrade to premium package with DSTV's rewards program and was told that said upgrade would take place on the next billing date which was on the 25th of same month. I never received it and after making an enquiry was told that it will be allocated on the 25th of January 2022 which is today, but still nothing. Not trying to make empty threats, but I am seriously thinking about cancelling my subscription
