No value for money

I contacted them on the 06/06/2022 to downgrade to Access option, using their automated telephonic system. After that I was redirected to the agent, who confirmed that I have been successfully downgraded and even gave me the amount to pay for Access channel. I even asked him to transfer the credit of the other smart card to that access payment which he agreed. Yesterday I noticed that the TV was still on compact plus but I told myself that maybe their system takes long to change/adjust. Then today 09/06/2022, when I switched on the TV I realised it has been disconnected. How come because they had to utilize my previous credit to pay for my Access channel, secondly I had called them several times on the 06/06/2022 to make sure that the downgrade is activated. I'm feeling so prejudiced and disrespected because I wasted almost R200 airtime calling them. What annoys me worse is that 1) They will charge me for reconnection and pro rata for compact plus for the day(s) it was still on when it's not my fault. 2) They have been sitting with my credit for years now, which I think if it was in the bank it would have accumulated interest now. Every time I communicate with multichoice the outcome is never what I expected. I'm beyond annoyed.
