GOOD DAY

I WOULD LIKE TO COMPLAIN REGARDING THE DSTV REWARDS FALLS REWARD. I WON A FREE PREMIUM UPGRADE AT NO CHARGE UNTIL THE 15TH OF JANUARY 2022. NOW I OWE THE REMAINING BALANCE OF R900. HOW? THE REWARD SAID NO CHARGE AND WILL BE AUTOMATICALLY DOWNGRADE. NOW WHEN I CALL I'M TOLD THAT"SYSTEM DOESN'T PICK UP". NOW I'M TOLD THAT I NEED TO DOWNGRADE AND PAY AN AMOUNT. HOW?. I'M GIVING MULTICHOICE 24 hours. Falls advertising
