Unhappy with service

I was in arears and I was offered 50% (R745) discount to be paid by the 31st October 2022. Which I paid as promised. After paying I have been pushed pillar to post to get my account re-activated and to have access to Cartrack app. Firstly I was told that it will take 40 days until credit is passed. During that period, I was called almost on daily basis demanding the full amount. As much as I explained to them each and every time that account has been settled and they said they will escalate to another department. Believe it or not after the mentioned 40 days I’m still being told that they will escalate to another department. After requesting them to call me and when they do, I have to explain same thing all over again each time. As I was typing this message at 11h21 today ****h January 2023) I received a call from Sifiso Nyembe and telling he will request his credit department to pass it. I have also requested him to give me his/her supervisors name which he refused. In closing, I’m not sure what to do anymore.
