DSTV USING DSTV REWARDS TO **** CUSTOMERS!!!

My viewing has been disconnected unfairly. I was rewarded an upgrade to premium by DStv Rewards in December 2021, the upgrade was done on 15 January 2022 for 30 days. On 13 February I received an sms from DStv saying I should pay R1290 but on 16 February I paid for my normal subscription(Compact) thinking that they would do the downgrade to my previous package automatically but my viewing was disconnected on 17 February saying I owe. I called the DStv call centre and contacted them also on Facebook regarding the disconnection and my viewing was reconnected on the 18 February but the balance I supposedly owe was not removed. My viewing has been disconnected again today and I am told to pay R519. I do not owed this. I have been incorrectly billed. The upgrade to premium according to DStv Rewards I was told was a FREE upgrade for 30 days. I DID NOT REQUEST FOR AN UPGRADE NOR DID I DO THE UPGRADE MYSELF. IT WAS A REWARD FROM DSTV REWARDS. So I am now being charged for the upgrade! DSTV!!!????
